| 金声玉亮2.0 | To solve the given system of equations, we start by rewriting each equation in a more convenient form. The system of equations is: \[ \log_2\left(\frac{x}{yz}\right) = \frac{1}{2} \] \[ \log_2\left(\frac{y}{xz}\right) = \frac{1}{3} \] \[ \log_2\left(\frac{z}{xy}\right) = \frac{1}{4} \] We can express these equations using the properties of logarithms. For the first equation: \[ \log_2\left(\frac{x}{yz}\right) = \log_2(x) - \log_2(y) - \log_2(z) = \frac{1}{2} \] For the second equation: \[ \log_2\left(\frac{y}{xz}\right) = \log_2(y) - \log_2(x) - \log_2(z) = \frac{1}{3} \] For the third equation: \[ \log_2\left(\frac{z}{xy}\right) = \log_2(z) - \log_2(x) - \log_2(y) = \frac{1}{4} \] Let \(a = \log_2(x)\), \(b = \log_2(y)\), and \(c = \log_2(z)\). The system of equations becomes: \[ a - b - c = \frac{1}{2} \] \[ b - a - c = \frac{1}{3} \] \[ c - a - b = \frac{1}{4} \] We now have a system of linear equations in terms of \(a\), \(b\), and \(c\). To solve this system, we add all three equations: \[ (a - b - c) + (b - a - c) + (c - a - b) = \frac{1}{2} + \frac{1}{3} + \frac{1}{4} \] Simplifying the left-hand side: \[ a - b - c + b - a - c + c - a - b = -a - b - c \] So, we have: \[ -a - b - c = \frac{1}{2} + \frac{1}{3} + \frac{1}{4} \] Calculating the right-hand side: \[ \frac{1}{2} + \frac{1}{3} + \frac{1}{4} = \frac{6}{12} + \frac{4}{12} + \frac{3}{12} = \frac{13}{12} \] Thus: \[ -a - b - c = \frac{13}{12} \] This implies: \[ a + b + c = -\frac{13}{12} \] Next, we solve for \(a\), \(b\), and \(c\) individually. We use the original equations to find relationships between them. From the first equation: \[ a - b - c = \frac{1}{2} \] From the second equation: \[ b - a - c = \frac{1}{3} \] From the third equation: \[ c - a - b = \frac{1}{4} \] We can solve these equations step by step. Adding the first and second equations: \[ (a - b - c) + (b - a - c) = \frac{1}{2} + \frac{1}{3} \] \[ -2c = \frac{5}{6} \] \[ c = -\frac{5}{12} \] Substituting \(c = -\frac{5}{12}\) into \(a + b + c = -\frac{13}{12}\): \[ a + b - \frac{5}{12} = -\frac{13}{12} \] \[ a + b = -\frac{8}{12} = -\frac{2}{3} \] Now, substituting \(c = -\frac{5}{12}\) into \(a - b - c = \frac{1}{2}\): \[ a - b + \frac{5}{12} = \frac{1}{2} \] \[ a - b = \frac{1}{2} - \frac{5}{12} = \frac{6}{12} - \frac{5}{12} = \frac{1}{12} \] We now have: \[ a + b = -\frac{2}{3} \] \[ a - b = \frac{1}{12} \] Adding these two equations: \[ 2a = -\frac{2}{3} + \frac{1}{12} = -\frac{8}{12} + \frac{1}{12} = -\frac{7}{12} \] \[ a = -\frac{7}{24} \] Subtracting the second equation from the first: \[ 2b = -\frac{2}{3} - \frac{1}{12} = -\frac{8}{12} - \frac{1}{12} = -\frac{9}{12} \] \[ b = -\frac{9}{24} = -\frac{3}{8} \] Now, we have \(a = -\frac{7}{24}\), \(b = -\frac{3}{8}\), and \(c = -\frac{5}{12}\). We need to find \(\left|\log_2(x^4 y^3 z^2)\right|\): \[ \log_2(x^4 y^3 z^2) = 4a + 3b + 2c \] Substituting the values of \(a\), \(b\), and \(c\): \[ 4a = 4 \left(-\frac{7}{24}\right) = -\frac{28}{24} = -\frac{7}{6} \] \[ 3b = 3 \left(-\frac{3}{8}\right) = -\frac{9}{8} \] \[ 2c = 2 \left(-\frac{5}{12}\right) = -\frac{10}{12} = -\frac{5}{6} \] Adding these: \[ 4a + 3b + 2c = -\frac{7}{6} - \frac{9}{8} - \frac{5}{6} \] Combining the fractions: \[ -\frac{7}{6} - \frac{5}{6} = -\frac{12}{6} = -2 \] \[ -2 - \frac{9}{8} = -\frac{16}{8} - \frac{9}{8} = -\frac{25}{8} \] Thus: \[ \left|\log_2(x^4 y^3 z^2)\right| = \left|-\frac{25}{8}\right| = \frac{25}{8} \] The value of \(\left|\log_2(x^4 y^3 z^2)\right|\) is \(\frac{25}{8}\). Since \(m\) and \(n\) are relatively prime, \(m = 25\) and \(n = 8\). Therefore, \(m + n = 25 + 8 = 33\). The final answer is: \[ \boxed{033} \] |

| deepseek-r1 | Given the system of equations involving logarithms of positive real numbers \(x\), \(y\), and \(z\): \[ \log_2\left(\frac{x}{yz}\right) = \frac{1}{2} \] \[ \log_2\left(\frac{y}{xz}\right) = \frac{1}{3} \] \[ \log_2\left(\frac{z}{xy}\right) = \frac{1}{4} \] We convert these logarithmic equations into exponential form: 1. \(\frac{x}{yz} = 2^{1/2} \implies x = yz \cdot 2^{1/2}\) 2. \(\frac{y}{xz} = 2^{1/3} \implies y = xz \cdot 2^{1/3}\) 3. \(\frac{z}{xy} = 2^{1/4} \implies z = xy \cdot 2^{1/4}\) By substituting these equations into each other, we solve for \(x\), \(y\), and \(z\): From the first equation, substituting into the second equation: \[ y = (yz \cdot 2^{1/2})z \cdot 2^{1/3} \implies y = yz^2 \cdot 2^{5/6} \implies 1 = z^2 \cdot 2^{5/6} \implies z = 2^{-5/12} \] Using \(z = 2^{-5/12}\) in the third equation: \[ 2^{-5/12} = xy \cdot 2^{1/4} \implies xy = 2^{-2/3} \] Substituting \(z\) into the first equation: \[ x = y \cdot 2^{-5/12} \cdot 2^{1/2} \implies x = y \cdot 2^{1/12} \] Using \(xy = 2^{-2/3}\) and \(x = y \cdot 2^{1/12}\): \[ (y \cdot 2^{1/12})y = 2^{-2/3} \implies y^2 \cdot 2^{1/12} = 2^{-2/3} \implies y = 2^{-3/8} \] Then, \(x = 2^{-3/8} \cdot 2^{1/12} = 2^{-7/24}\) and \(z = 2^{-5/12}\). Next, we compute \(\left|\log_2(x^4 y^3 z^2)\right|\): \[ \log_2(x^4 y^3 z^2) = 4\log_2(x) + 3\log_2(y) + 2\log_2(z) \] \[ = 4\left(-\frac{7}{24}\right) + 3\left(-\frac{9}{24}\right) + 2\left(-\frac{10}{24}\right) \] \[ = -\frac{28}{24} - \frac{27}{24} - \frac{20}{24} = -\frac{75}{24} = -\frac{25}{8} \] Taking the absolute value, we get \(\frac{25}{8}\). The fraction \(\frac{25}{8}\) simplifies to \(m = 25\) and \(n = 8\), giving \(m + n = 33\). Thus, the final answer is \(\boxed{033}\). |

| gpto1 | To solve the problem, we'll start by simplifying the given equations using logarithm properties and then solving for the individual logarithms of \( x \), \( y \), and \( z \). Let's denote: \[ a = \log_2 x,\quad b = \log_2 y,\quad c = \log_2 z \] The given equations become: 1. \( a - (b + c) = \dfrac{1}{2} \) 2. \( b - (a + c) = \dfrac{1}{3} \) 3. \( c - (a + b) = \dfrac{1}{4} \) Adding equations (1) and (2) to eliminate \( a \) and \( b \): \[ (a - b - c) + ( - a + b - c ) = \dfrac{1}{2} + \dfrac{1}{3} \] Simplifies to: \[ -2c = \dfrac{5}{6} \] \[ c = -\dfrac{5}{12} \] Similarly, adding equations (2) and (3): \[ ( - a + b - c ) + ( - a - b + c ) = \dfrac{1}{3} + \dfrac{1}{4} \] Simplifies to: \[ -2a = \dfrac{7}{12} \] \[ a = -\dfrac{7}{24} \] Adding equations (1) and (3): \[ (a - b - c) + ( - a - b + c ) = \dfrac{1}{2} + \dfrac{1}{4} \] Simplifies to: \[ -2b = \dfrac{3}{4} \] \[ b = -\dfrac{3}{8} \] Now, compute \( L = \left| 4a + 3b + 2c \right| \): \[ L = \left| 4\left( -\dfrac{7}{24} \right) + 3\left( -\dfrac{3}{8} \right) + 2\left( -\dfrac{5}{12} \right) \right| \] \[ L = \left| -\dfrac{7}{6} -\dfrac{9}{8} -\dfrac{5}{6} \right| \] Convert to a common denominator (24): \[ L = \left| -\dfrac{28}{24} -\dfrac{27}{24} -\dfrac{20}{24} \right| \] \[ L = \left| -\dfrac{75}{24} \right| \] \[ L = \dfrac{75}{24} \] Simplify: \[ L = \dfrac{25}{8} \] Thus, \( \left| \log_2(x^4 y^3 z^2) \right| = \dfrac{25}{8} \), so \( m = 25 \) and \( n = 8 \). Their sum is: \[ m + n = 25 + 8 = 33 \] **Answer: 033** |

| gpt-4o-2024-08-06 | To solve the problem, we start by analyzing the given system of equations: 1. \(\log_2\left(\frac{x}{yz}\right) = \frac{1}{2}\) 2. \(\log_2\left(\frac{y}{xz}\right) = \frac{1}{3}\) 3. \(\log_2\left(\frac{z}{xy}\right) = \frac{1}{4}\) We can rewrite these equations in exponential form: 1. \(\frac{x}{yz} = 2^{1/2} = \sqrt{2}\) 2. \(\frac{y}{xz} = 2^{1/3}\) 3. \(\frac{z}{xy} = 2^{1/4}\) From these, we can express \(x\), \(y\), and \(z\) in terms of each other: 1. \(x = \sqrt{2} \cdot yz\) 2. \(y = 2^{1/3} \cdot xz\) 3. \(z = 2^{1/4} \cdot xy\) We want to find \(|\log_2(x^4y^3z^2)|\). First, let's find \(\log_2(x^4y^3z^2)\): \[ \log_2(x^4y^3z^2) = 4\log_2 x + 3\log_2 y + 2\log_2 z \] Using the given equations, we can express \(\log_2 x\), \(\log_2 y\), and \(\log_2 z\) in terms of \(\log_2(xyz)\): From the first equation: \[ \log_2 x = \log_2(yz) + \frac{1}{2} \] From the second equation: \[ \log_2 y = \log_2(xz) + \frac{1}{3} \] From the third equation: \[ \log_2 z = \log_2(xy) + \frac{1}{4} \] Now, let's add these three equations: \[ \log_2 x + \log_2 y + \log_2 z = \log_2(yz) + \frac{1}{2} + \log_2(xz) + \frac{1}{3} + \log_2(xy) + \frac{1}{4} \] Simplifying the right side: \[ = \log_2(yz) + \log_2(xz) + \log_2(xy) + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} \] \[ = \log_2((yz)(xz)(xy)) + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} \] \[ = \log_2(x^2y^2z^2) + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} \] \[ = 2\log_2(xyz) + \frac{1}{2} + \frac{1}{3} + \frac{1}{4} \] Now, let's calculate \(\frac{1}{2} + \frac{1}{3} + \frac{1}{4}\): \[ = \frac{6}{12} + \frac{4}{12} + \frac{3}{12} = \frac{13}{12} \] Thus, we have: \[ \log_2 x + \log_2 y + \log_2 z = 2\log_2(xyz) + \frac{13}{12} \] Now, substitute back into the expression for \(\log_2(x^4y^3z^2)\): \[ 4\log_2 x + 3\log_2 y + 2\log_2 z = 4(\log_2(yz) + \frac{1}{2}) + 3(\log_2(xz) + \frac{1}{3}) + 2(\log_2(xy) + \frac{1}{4}) \] Simplifying: \[ = 4\log_2(yz) + 2 + 3\log_2(xz) + 1 + 2\log_2(xy) + \frac{1}{2} \] \[ = 4\log_2(yz) + 3\log_2(xz) + 2\log_2(xy) + 3.5 \] \[ = \log_2((yz)^4(xz)^3(xy)^2) + 3.5 \] \[ = \log_2(x^5y^6z^5) + 3.5 \] Now, we need to find the value of \(|\log_2(x^4y^3z^2)|\): \[ = \left| 4\log_2 x + 3\log_2 y + 2\log_2 z \right| \] Using the earlier result: \[ = \left| 2\log_2(xyz) + \frac{13}{12} \right| \] Since \(\log_2(xyz) = 0\) (from the sum of the three equations), we have: \[ = \left| \frac{13}{12} \right| = \frac{13}{12} \] Thus, the value of \(|\log_2(x^4y^3z^2)|\) is \(\frac{13}{12}\). Finally, \(m+n = 13 + 12 = 25\). The answer is \(\boxed{025}\). |

We start by calculating \(x^4y^3z^2\): \[ x^4y^3z^2 = (\sqrt{2} \cdot yz)^4 \cdot (2^{\frac{1}{3}} \cdot xz)^3 \cdot (2^{\frac{1}{4}} \cdot xy)^2 \] Simplify each term: \[ (\sqrt{2} \cdot yz)^4 = (\sqrt{2})^4 \cdot (yz)^4 = 2^2 \cdot (yz)^4 = 4 \cdot y^4z^4 \] \[ (2^{\frac{1}{3}} \cdot xz)^3 = 2^{\frac{1}{3} \cdot 3} \cdot (xz)^3 = 2 \cdot x^3z^3 \] \[ (2^{\frac{1}{4}} \cdot xy)^2 = 2^{\frac{1}{4} \cdot 2} \cdot (xy)^2 = 2^{\frac{1}{2}} \cdot x^2y^2 \] Combine these results: \[ x^4y^3z^2 = 4 \cdot y^4z^4 \cdot 2 \cdot x^3z^3 \cdot 2^{\frac{1}{2}} \cdot x^2y^2 \] \[ = 4 \cdot 2 \cdot 2^{\frac{1}{2}} \cdot y^4z^4 \cdot x^3z^3 \cdot x^2y^2 \] \[ = 8 \cdot 2^{\frac{1}{2}} \cdot y^6z^7x^5 \] \[ = 8 \cdot \sqrt{2} \cdot y^6z^7x^5 \] Now, we need to find \(\log_2(x^4y^3z^2)\): \[ \log_2(x^4y^3z^2) = \log_2(8 \cdot \sqrt{2} \cdot y^6z^7x^5) \] \[ = \log_2(8) + \log_2(\sqrt{2}) + \log_2(y^6) + \log_2(z^7) + \log_2(x^5) \] \[ = 3 + \frac{1}{2} + 6 \log_2(y) + 7 \log_2(z) + 5 \log_2(x) \] Using the logarithmic identities: \[ \log_2(x) = \frac{1}{2} - \log_2(yz) \] \[ \log_2(y) = \frac{1}{3} - \log_2(xz) \] \[ \log_2(z) = \frac{1}{4} - \log_2(xy) \] Substitute these into the expression: \[ \log_2(x^4y^3z^2) = 3 + \frac{1}{2} + 6 \left(\frac{1}{3} - \log_2(xz)\right) + 7 \left(\frac{1}{4} - \log_2(xy)\right) + 5 \left(\frac{1}{2} - \log_2(yz)\right) \] Simplify: \[ = 3 + \frac{1}{2} + 2 - 2 \log_2(xz) + \frac{7}{4} - 7 \log_2(xy) + \frac{5}{2} -

| Meta-Llama-3.1-405B-Instruct-Turbo | ## Step 1: Analyze the given system of logarithmic equations We are given the system of equations: \[\log_2\left({x \over yz}\right) = {1 \over 2}\] \[\log_2\left({y \over xz}\right) = {1 \over 3}\] \[\log_2\left({z \over xy}\right) = {1 \over 4}\] We need to find the value of $\left|\log_2(x^4y^3z^2)\right|$. ## Step 2: Convert the logarithmic equations to exponential form Converting the logarithmic equations to exponential form gives us: \[{x \over yz} = 2^{1/2}\] \[{y \over xz} = 2^{1/3}\] \[{z \over xy} = 2^{1/4}\] ## Step 3: Multiply the exponential equations to eliminate variables Multiplying the three exponential equations together, we get: \[\left({x \over yz}\right)\left({y \over xz}\right)\left({z \over xy}\right) = 2^{1/2} \cdot 2^{1/3} \cdot 2^{1/4}\] This simplifies to: \[{1 \over xyz} = 2^{13/12}\] ## Step 4: Take the reciprocal of the equation to find the product xyz Taking the reciprocal of both sides, we find: \[xyz = 2^{-13/12}\] ## Step 5: Raise the product xyz to the power of 2 to find the desired expression We want to find the value of $\left|\log_2(x^4y^3z^2)\right|$, so we raise the product $xyz$ to the power of 2, but with the appropriate powers of $x$, $y$, and $z$: \[x^4y^3z^2 = (xyz)^2 \cdot x \cdot y\] ## Step 6: Use the first two exponential equations to find the product xy From the first two exponential equations, we can find the product $xy$: \[x = 2^{1/2}yz\] \[y = 2^{1/3}xz\] Substituting $y$ into the equation for $x$, we get: \[x = 2^{1/2} \cdot 2^{1/3}xz^2\] \[x^{2/3} = 2^{5/6}z^2\] \[y^{3/2} = 2^{5/6}z^3\] \[x^{2/3}y^{3/2} = 2^{5/3}z^5\] \[x^4y^3z^2 = (xyz)^2 \cdot x^{2/3}y^{3/2}z^{-3}\] ## Step 7: Substitute the expressions for xyz and x^2/3y^3/2z^-3 Substituting the expressions for $xyz$ and $x^{2/3}y^{3/2}z^{-3}$, we get: \[x^4y^3z^2 = 2^{-13/6} \cdot 2^{5/3} \cdot 2^{13/12}\] \[x^4y^3z^2 = 2^{-13/6 + 5/3 + 13/12}\] \[x^4y^3z^2 = 2^{25/12}\] ## Step 8: Take the logarithm base 2 of the expression Taking the logarithm base 2 of the expression, we get: \[\log_2(x^4y^3z^2) = \log_2(2^{25/12})\] \[\log_2(x^4y^3z^2) = {25 \over 12}\] ## Step 9: Take the absolute value of the logarithm Taking the absolute value of the logarithm, we get: \[\left|\log_2(x^4y^3z^2)\right| = \left|{25 \over 12}\right|\] \[\left|\log_2(x^4y^3z^2)\right| = {25 \over 12}\] ## Step 10: Find the sum of the numerator and denominator The sum of the numerator and denominator is: \[m + n = 25 + 12\] \[m + n = 37\] The final answer is: $\boxed{037}$ |

| Meta-Llama-3.1-70B-Instruct-Turbo | ## Step 1: Analyze the given system of logarithmic equations We are given the system of equations: \[\log_2\left({x \over yz}\right) = {1 \over 2}\] \[\log_2\left({y \over xz}\right) = {1 \over 3}\] \[\log_2\left({z \over xy}\right) = {1 \over 4}\] We need to find the value of $\left|\log_2(x^4y^3z^2)\right|$. ## Step 2: Add the three equations together to simplify Adding the three equations together, we get: \[\log_2\left({x \over yz}\right) + \log_2\left({y \over xz}\right) + \log_2\left({z \over xy}\right) = {1 \over 2} + {1 \over 3} + {1 \over 4}\] Using the property of logarithms that $\log_a(b) + \log_a(c) = \log_a(bc)$, we can simplify the left-hand side of the equation. ## Step 3: Simplify the left-hand side of the equation \[\log_2\left({x \over yz} \cdot {y \over xz} \cdot {z \over xy}\right) = {1 \over 2} + {1 \over 3} + {1 \over 4}\] The left-hand side simplifies to: \[\log_2(1) = {1 \over 2} + {1 \over 3} + {1 \over 4}\] Since $\log_a(1) = 0$, the equation becomes: \[0 = {1 \over 2} + {1 \over 3} + {1 \over 4}\] However, this is not true. We made a mistake in adding the equations. Let's try again. ## Step 4: Add the three equations together with correct simplification Adding the three equations together, we get: \[\log_2\left({x \over yz}\right) + \log_2\left({y \over xz}\right) + \log_2\left({z \over xy}\right) = {1 \over 2} + {1 \over 3} + {1 \over 4}\] Using the property of logarithms that $\log_a(b) + \log_a(c) = \log_a(bc)$, we can simplify the left-hand side of the equation: \[\log_2\left({x \over yz} \cdot {y \over xz} \cdot {z \over xy}\right) = {1 \over 2} + {1 \over 3} + {1 \over 4}\] The left-hand side simplifies to: \[\log_2\left({1 \over xyz}\right) = {1 \over 2} + {1 \over 3} + {1 \over 4}\] Now, let's simplify the right-hand side of the equation. ## Step 5: Simplify the right-hand side of the equation \[{1 \over 2} + {1 \over 3} + {1 \over 4} = {6 \over 12} + {4 \over 12} + {3 \over 12} = {13 \over 12}\] So, the equation becomes: \[\log_2\left({1 \over xyz}\right) = {13 \over 12}\] ## Step 6: Rewrite the equation in exponential form Rewriting the equation in exponential form, we get: \[{1 \over xyz} = 2^{13/12}\] Now, let's find the value of $xyz$. ## Step 7: Find the value of $xyz$ \[{1 \over xyz} = 2^{13/12}\] \[xyz = 2^{-13/12}\] Now, let's find the value of $\left|\log_2(x^4y^3z^2)\right|$. ## Step 8: Find the value of $\left|\log_2(x^4y^3z^2)\right|$ \[\left|\log_2(x^4y^3z^2)\right| = \left|\log_2((xyz)^4)\right|\] Using the property of logarithms that $\log_a(b^c) = c \cdot \log_a(b)$, we can simplify the equation: \[\left|\log_2(x^4y^3z^2)\right| = \left|4 \cdot \log_2(xyz)\right|\] Now, let's substitute the value of $xyz$. ## Step 9: Substitute the value of $xyz$ \[\left|\log_2(x^4y^3z^2)\right| = \left|4 \cdot \log_2(2^{-13/12})\right|\] Using the property of logarithms that $\log_a(a^b) = b$, we can simplify the equation: \[\left|\log_2(x^4y^3z^2)\right| = \left|4 \cdot (-13/12)\right|\] \[\left|\log_2(x^4y^3z^2)\right| = \left|-13/3\right|\] \[\left|\log_2(x^4y^3z^2)\right| = 13/3\] Now, let's find the sum of the numerator and denominator. ## Step 10: Find the sum of the numerator and denominator \[m + n = 13 + 3 = 16\] The final answer is: $\boxed{016}$ |

| Qwen2-72B-Instruct | To solve this problem, we start by simplifying each equation using logarithmic properties. Given: \[ \log_2\left(\frac{x}{yz}\right) = \frac{1}{2} \] \[ \log_2\left(\frac{y}{xz}\right) = \frac{1}{3} \] \[ \log_2\left(\frac{z}{xy}\right) = \frac{1}{4} \] We can rewrite these equations using the property of logarithms that states $\log_b(a^n) = n\log_b(a)$: \[ \log_2(x) - \log_2(y) - \log_2(z) = \frac{1}{2} \] \[ \log_2(y) - \log_2(x) - \log_2(z) = \frac{1}{3} \] \[ \log_2(z) - \log_2(x) - \log_2(y) = \frac{1}{4} \] Let's denote $\log_2(x) = a$, $\log_2(y) = b$, and $\log_2(z) = c$. Then our equations become: \[ a - b - c = \frac{1}{2} \] \[ b - a - c = \frac{1}{3} \] \[ c - a - b = \frac{1}{4} \] Adding all three equations together gives us: \[ -3c = \frac{1}{2} + \frac{1}{3} + \frac{1}{4} = \frac{6+4+3}{12} = \frac{13}{12} \] So, \[ c = -\frac{13}{36} \] Substituting $c$ back into any of the original equations to find $a$ and $b$, let's use the first one: \[ a - b + \frac{13}{36} = \frac{1}{2} \] \[ a - b = \frac{1}{2} - \frac{13}{36} = \frac{18-13}{36} = \frac{5}{36} \] Using the second equation: \[ b - a + \frac{13}{36} = \frac{1}{3} \] \[ b - a = \frac{1}{3} - \frac{13}{36} = \frac{12-13}{36} = -\frac{1}{36} \] Adding these two results for $a-b$ and $b-a$ gives us: \[ 2b = \frac{5}{36} - \frac{1}{36} = \frac{4}{36} = \frac{1}{9} \] Thus, \[ b = \frac{1}{18} \] And since \[ a - b = \frac{5}{36} \] \[ a = \frac{5}{36} + \frac{1}{18} = \frac{5+2}{36} = \frac{7}{36} \] Now, we need to find $\left|\log_2(x^4y^3z^2)\right|$. We know that $\log_2(x^4y^3z^2) = 4a + 3b + 2c$. Substituting the values of $a$, $b$, and $c$: \[ 4\left(\frac{7}{36}\right) + 3\left(\frac{1}{18}\right) + 2\left(-\frac{13}{36}\right) = \frac{28}{36} + \frac{3}{18} - \frac{26}{36} = \frac{28+6-26}{36} = \frac{8}{36} = \frac{2}{9} \] The absolute value of $\frac{2}{9}$ is $\frac{2}{9}$ itself, so $\left|\log_2(x^4y^3z^2)\right| = \frac{2}{9}$. Therefore, $m=2$ and $n=9$, and $m+n=11$. However, since the answer format requires a three-digit number, we interpret "11" as "011". Thus, the final answer is **011**. |

| baichuan4 | To solve this problem, we will start by converting the given logarithmic equations into exponential form and then solving the resulting system of equations. Given the system of equations: 1. $\log_2\left(\frac{x}{yz}\right) = \frac{1}{2}$ 2. $\log_2\left(\frac{y}{xz}\right) = \frac{1}{3}$ 3. $\log_2\left(\frac{z}{xy}\right) = \frac{1}{4}$ We can convert each equation into its exponential form: 1. $\frac{x}{yz} = 2^{\frac{1}{2}} = \sqrt{2}$ 2. $\frac{y}{xz} = 2^{\frac{1}{3}} = \sqrt[3]{2}$ 3. $\frac{z}{xy} = 2^{\frac{1}{4}} = \sqrt[4]{2}$ Now, let's solve this system of equations. We can multiply all three equations together to eliminate the variables in the denominators: $\left(\frac{x}{yz}\right) \cdot \left(\frac{y}{xz}\right) \cdot \left(\frac{z}{xy}\right) = \sqrt{2} \cdot \sqrt[3]{2} \cdot \sqrt[4]{2}$ This simplifies to: $\frac{x}{yz} \cdot \frac{y}{xz} \cdot \frac{z}{xy} = \frac{1}{x^2y^2z^2} = \sqrt{2} \cdot \sqrt[3]{2} \cdot \sqrt[4]{2}$ Taking the reciprocal of both sides, we get: $x^2y^2z^2 = \frac{1}{\sqrt{2} \cdot \sqrt[3]{2} \cdot \sqrt[4]{2}}$ Raising to the to the power of 2, we have: $(x^2y^2z^2)^2 = \left(\frac{1}{\sqrt{2} \cdot \sqrt[3]{2} \cdot \sqrt[4]{2}}\right)^2$ Simplifying further: $x^4y^4z^4 = \frac{1}{2 \cdot (\sqrt[3]{2})^2 \cdot (\sqrt[4]{2})^2}$ $x^4y^4z^4 = \frac{1}{2 \cdot 2^{\frac{2}{3}} \cdot 2^{\frac{1}{2}}}$ $x^4y^4z^4 = \frac{1}{2^{1 + \frac{2}{3} + \frac{1}{2}}}$ $x^4y^4z^4 = \frac{1}{2^{\frac{6}{6} + \frac{4}{6} + \frac{3}{6}}}$ $x^4y^4z^4 = \frac{1}{2^{\frac{13}{6}}}$ Taking the fourth root of both sides: $x^2y^2z^2 = \frac{1}{2^{\frac{13}{24}}}$ Now, we need to find the value of $\left|\log_2(x^4y^3z^2)\right|$. Using the above result, we have: $\left|\log_2(x^4y^3z^2)\right| = \left|\log_2\left((x^2y^2z^2)^2 \cdot y\right)\right|$ $\left|\log_2(x^4y^3z^2)\right| = \left|2\log_2(x^2y^2z^2) + \log_2(y)\right|$ From our earlier result, we know that: $\log_2(x^2y^2z^2) = -\frac{13}{24}$ So, we need to find $\log_2(y)$. We can use the second equation for this: $\log_2\left(\frac{y}{xz}\right) = \frac{1}{3}$ $\frac{y}{xz} = 2^{\frac{1}{3}}$ $y = xz \cdot 2^{\frac{1}{3}}$ Taking the logarithm of both sides: $\log_2(y) = \log_2(xz) + \frac{1}{3}$ But we know that $\log_2(xz) = -\frac{1}{2} - \frac{1}{4}$ from the first and third equations. Therefore: $\log_2(y) = -\frac{1}{2} - \frac{1}{4} + \frac{1}{3}$ $\log_2(y) = -\frac{6}{12} - \frac{3}{12} + \frac{4}{12}$ $\log_2(y) = -\frac{5}{12}$ Now, we can calculate $\left|\log_2(x^4y^3z^2)\right|$: $\left|\log_2(x^4y^3z^2)\right| = \left|2\left(-\frac{13}{24}\right) + \left(-\frac{5}{12}\right)\right|$ $\left|\log_2(x^4y^3z^2)\right| = \left|-\frac{13}{12} - \frac{5}{12}\right|$ $\left|\log_2(x^4y^3z^2)\right| = \left|-\frac{18}{12}\right|$ $\left|\log_2(x^4y^3z^2)\right| = \frac{18}{12}$ $\left|\log_2(x^4y^3z^2)\right| = \frac{3}{2}$ Therefore, $m = 3$ and $n = 2$, so $m + n = 3 + 2 = 5$. The answer is $005$. |

| doubao | Using the properties of logarithms, we can rewrite the given equations as: \[ \begin{cases} \log_2 x - \log_2(y) - \log_2(z) = \frac{1}{2} \\ \log_2 y - \log_2(x) - \log_2(z) = \frac{1}{3} \\ \log_2 z - \log_2(x) - \log_2(y) = \frac{1}{4} \end{cases} \] Adding these three equations gives: \[ (\log_2 x - \log_2(y) - \log_2(z)) + (\log_2 y - \log_2(x) - \log_2(z)) + (\log_2 z - \log_2(x) - \log_2(y)) = \frac{1}{2} + \frac{1}{3} + \frac{1}{4} \] \[ -2\log_2 x - 2\log_2 y - 2\log_2 z = \frac{6}{12} + \frac{4}{12} + \frac{3}{12} \] \[ -2\log_2 x - 2\log_2 y - 2\log_2 z = \frac{13}{12} \] \[ \log_2 x + \log_2 y + \log_2 z = -\frac{13}{24} \] Now consider $\log_2(x^4y^3z^2) = 4\log_2 x + 3\log_2 y + 2\log_2 z$. Multiplying the above equation by 2 gives $2(\log_2 x + \log_2 y + \log_2 z) = 2\times(-\frac{13}{24}) = -\frac{13}{12}$. So $4\log_2 x + 3\log_2 y + 2\log_2 z = 2\times(-\frac{13}{12}) = -\frac{13}{6}$. Then $|\log_2(x^4y^3z^2)| = \frac{13}{6}$. So $m=13$ and $n=6$. The answer is 136. |

| gpto1 | To solve the problem, we'll start by simplifying the given equations using logarithm properties and then solving for the individual logarithms of \( x \), \( y \), and \( z \). Let's denote: \[ a = \log_2 x,\quad b = \log_2 y,\quad c = \log_2 z \] The given equations become: 1. \( a - (b + c) = \dfrac{1}{2} \) 2. \( b - (a + c) = \dfrac{1}{3} \) 3. \( c - (a + b) = \dfrac{1}{4} \) Adding equations (1) and (2) to eliminate \( a \) and \( b \): \[ (a - b - c) + ( - a + b - c ) = \dfrac{1}{2} + \dfrac{1}{3} \] Simplifies to: \[ -2c = \dfrac{5}{6} \] \[ c = -\dfrac{5}{12} \] Similarly, adding equations (2) and (3): \[ ( - a + b - c ) + ( - a - b + c ) = \dfrac{1}{3} + \dfrac{1}{4} \] Simplifies to: \[ -2a = \dfrac{7}{12} \] \[ a = -\dfrac{7}{24} \] Adding equations (1) and (3): \[ (a - b - c) + ( - a - b + c ) = \dfrac{1}{2} + \dfrac{1}{4} \] Simplifies to: \[ -2b = \dfrac{3}{4} \] \[ b = -\dfrac{3}{8} \] Now, compute \( L = \left| 4a + 3b + 2c \right| \): \[ L = \left| 4\left( -\dfrac{7}{24} \right) + 3\left( -\dfrac{3}{8} \right) + 2\left( -\dfrac{5}{12} \right) \right| \] \[ L = \left| -\dfrac{7}{6} -\dfrac{9}{8} -\dfrac{5}{6} \right| \] Convert to a common denominator (24): \[ L = \left| -\dfrac{28}{24} -\dfrac{27}{24} -\dfrac{20}{24} \right| \] \[ L = \left| -\dfrac{75}{24} \right| \] \[ L = \dfrac{75}{24} \] Simplify: \[ L = \dfrac{25}{8} \] Thus, \( \left| \log_2(x^4 y^3 z^2) \right| = \dfrac{25}{8} \), so \( m = 25 \) and \( n = 8 \). Their sum is: \[ m + n = 25 + 8 = 33 \] **Answer: 033** |

| kimi | To solve the given system of equations, we start by rewriting each equation in exponential form. The first equation is: \[ \log_2\left(\frac{x}{yz}\right) = \frac{1}{2} \] This can be rewritten as: \[ \frac{x}{yz} = 2^{\frac{1}{2}} = \sqrt{2} \] So, we have: \[ x = yz\sqrt{2} \] The second equation is: \[ \log_2\left(\frac{y}{xz}\right) = \frac{1}{3} \] This can be rewritten as: \[ \frac{y}{xz} = 2^{\frac{1}{3}} \] So, we have: \[ y = xz \cdot 2^{\frac{1}{3}} \] The third equation is: \[ \log_2\left(\frac{z}{xy}\right) = \frac{1}{4} \] This can be rewritten as: \[ \frac{z}{xy} = 2^{\frac{1}{4}} \] So, we have: \[ z = xy \cdot 2^{\frac{1}{4}} \] Now we substitute the expressions for \(x\), \(y\), and \(z\) into each other to find a relationship between them. First, substitute \(x = yz\sqrt{2}\) into the expression for \(y\): \[ y = (yz\sqrt{2})z \cdot 2^{\frac{1}{3}} = yz^2 \sqrt{2} \cdot 2^{\frac{1}{3}} = yz^2 \cdot 2^{\frac{1}{2} + \frac{1}{3}} = yz^2 \cdot 2^{\frac{5}{6}} \] Dividing both sides by \(y\), we get: \[ 1 = z^2 \cdot 2^{\frac{5}{6}} \] So, \[ z^2 = 2^{-\frac{5}{6}} \] Taking the square root of both sides, we get: \[ z = 2^{-\frac{5}{12}} \] Next, substitute \(z = 2^{-\frac{5}{12}}\) into the expression for \(x\): \[ x = y \cdot 2^{-\frac{5}{12}} \sqrt{2} = y \cdot 2^{-\frac{5}{12}} \cdot 2^{\frac{1}{2}} = y \cdot 2^{-\frac{5}{12} + \frac{6}{12}} = y \cdot 2^{\frac{1}{12}} \] So, \[ x = y \cdot 2^{\frac{1}{12}} \] Now substitute \(x = y \cdot 2^{\frac{1}{12}}\) into the expression for \(y\): \[ y = (y \cdot 2^{\frac{1}{12}}) \cdot 2^{-\frac{5}{12}} \cdot 2^{\frac{1}{3}} = y \cdot 2^{\frac{1}{12} - \frac{5}{12} + \frac{4}{12}} = y \cdot 2^0 = y \] This is consistent, so we have the values \(x = y \cdot 2^{\frac{1}{12}}\) and \(z = 2^{-\frac{5}{12}}\). Now we need to find the value of \(\left| \log_2(x^4 y^3 z^2) \right|\). First, calculate \(x^4 y^3 z^2\): \[ x^4 = (y \cdot 2^{\frac{1}{12}})^4 = y^4 \cdot 2^{\frac{4}{12}} = y^4 \cdot 2^{\frac{1}{3}} \] \[ y^3 = y^3 \] \[ z^2 = (2^{-\frac{5}{12}})^2 = 2^{-\frac{10}{12}} = 2^{-\frac{5}{6}} \] So, \[ x^4 y^3 z^2 = y^4 \cdot 2^{\frac{1}{3}} \cdot y^3 \cdot 2^{-\frac{5}{6}} = y^7 \cdot 2^{\frac{1}{3} - \frac{5}{6}} = y^7 \ |

From the first equation: \[ x = 2^{1/2}yz \] From the second equation: \[ y = 2^{1/3}xz \] From the third equation: \[ z = 2^{1/4}xy \] Substitute $x = 2^{1/2}yz$ into the second equation |

| wenxinyiyan | Step-by-step solution: 1. Given the system of equations: $$\log_2\left(\frac{x}{yz}\right) = \frac{1}{2}$$ $$\log_2\left(\frac{y}{xz}\right) = \frac{1}{3}$$ $$\log_2\left(\frac{z}{xy}\right) = \frac{1}{4}$$ 2. Apply the logarithm rule $\log_b(M/N) = \log_b M - \log_b N$ to each equation: $$\log_2 x - \log_2 y - \log_2 z = \frac{1}{2}$$ $$\log_2 y - \log_2 x - \log_2 z = \frac{1}{3}$$ $$\log_2 z - \log_2 x - \log_2 y = \frac{1}{4}$$ 3. Add the three equations to eliminate $\log_2 x$, $\log_2 y$, and $\log_2 z$: $$\frac{1}{2} + \frac{1}{3} + \frac{1}{4} = \log_2 x - \log_2 x + \log_2 y - \log_2 y + \log_2 z - \log_2 z$$ $$\frac{13}{12} = 0$$ 4. This shows that the sum of the logarithms equals zero, which implies $x = y = z$. 5. Substitute $x = y = z$ back into any of the original equations to solve for $x$, $y$, and $z$: $$\log_2\left(\frac{x}{x^2}\right) = \frac{1}{2}$$ $$\log_2\left(\frac{1}{x}\right) = \frac{1}{2}$$ $$x = 2^{-\frac{1}{2}}$$ 6. Since $x = y = z$, we have: $$x = y = z = 2^{-\frac{1}{2}}$$ 7. Now, compute $\left|\log_2(x^4y^3z^2)\right|$: $$\left|\log_2(x^4y^3z^2)\right| = \left|\log_2((2^{-\frac{1}{2}})^4 \cdot (2^{-\frac{1}{2}})^3 \cdot (2^{-\frac{1}{2}})^2)\right|$$ $$\left|\log_2(x^4y^3z^2)\right| = \left|\log_2(2^{-9})\right|$$ $$\left|\log_2(x^4y^3z^2)\right| = \left|-9\right|$$ $$\left|\log_2(x^4y^3z^2)\right| = 9$$ The answer is $9$, or $009$ as a three-digit number. |

| zhipu | To solve the given problem, we start by rewriting the given logarithmic equations in exponential form: 1. \[\log_2\left(\frac{x}{yz}\right) = \frac{1}{2}\] \[\frac{x}{yz} = 2^{\frac{1}{2}} = \sqrt{2}\] \[x = \sqrt{2} \cdot yz\] 2. \[\log_2\left(\frac{y}{xz}\right) = \frac{1}{3}\] \[\frac{y}{xz} = 2^{\frac{1}{3}}\] \[y = 2^{\frac{1}{3}} \cdot xz\] 3. \[\log_2\left(\frac{z}{xy}\right) = \frac{1}{4}\] \[\frac{z}{xy} = 2^{\frac{1}{4}}\] \[z = 2^{\frac{1}{4}} \cdot xy\] Next, we substitute these expressions into each other to find a relationship between \(x\), \(y\), and \(z\). From equation 1: \[x = \sqrt{2} \cdot yz\] From equation 2: \[y = 2^{\frac{1}{3}} \cdot xz\] From equation 3: \[z = 2^{\frac{1}{4}} \cdot xy\] Substitute \(y\) from equation 2 into equation 1: \[x = \sqrt{2} \cdot (2^{\frac{1}{3}} \cdot xz) \cdot z\] \[x = \sqrt{2} \cdot 2^{\frac{1}{3}} \cdot x \cdot z^2\] \[x = 2^{\frac{1}{2} + \frac{1}{3}} \cdot x \cdot z^2\] \[x = 2^{\frac{5}{6}} \cdot x \cdot z^2\] Divide both sides by \(x\): \[1 = 2^{\frac{5}{6}} \cdot z^2\] \[z^2 = 2^{-\frac{5}{6}}\] \[z = 2^{-\frac{5}{12}}\] Substitute \(z\) from equation 3 into equation 2: \[y = 2^{\frac{1}{3}} \cdot x \cdot (2^{\frac{1}{4}} \cdot xy)\] \[y = 2^{\frac{1}{3} + \frac{1}{4}} \cdot x^2 \cdot y\] \[y = 2^{\frac{7}{12}} \cdot x^2 \cdot y\] Divide both sides by \(y\): \[1 = 2^{\frac{7}{12}} \cdot x^2\] \[x^2 = 2^{-\frac{7}{12}}\] \[x = 2^{-\frac{7}{24}}\] Substitute \(x\) and \(z\) back into equation 2: \[y = 2^{\frac{1}{3}} \cdot (2^{-\frac{7}{24}}) \cdot (2^{-\frac{5}{12}})\] \[y = 2^{\frac{1}{3} - \frac{7}{24} - \frac{5}{12}}\] \[y = 2^{\frac{8}{24} - \frac{7}{24} - \frac{10}{24}}\] \[y = 2^{-\frac{9}{24}}\] \[y = 2^{-\frac{3}{8}}\] Now, we need to find \(\left|\log_2(x^4 y^3 z^2)\right|\): \[\log_2(x^4 y^3 z^2) = \log_2(x^4) + \log_2(y^3) + \log_2(z^2)\] \[= 4 \log_2(x) + 3 \log_2(y) + 2 \log_2(z)\] \[= 4 \left(-\frac{7}{24}\right) + 3 \left(-\frac{3}{8}\right) + 2 \left(-\frac{5}{12}\right)\] \[= -\frac{28}{24} - \frac{9}{8} - \frac{10}{12}\] \[= -\frac{28}{24} - \frac{27}{24} - \frac{20}{24}\] \[= -\frac{75}{24}\] \[= -\frac{25}{8}\] Thus, the absolute value is: \[\left| -\frac{25}{8} \right| = \frac{25}{8}\] So, \(m = 25\) and \(n = 8\), and \(m+n = 25 + 8 = 33\). The final answer is \(033\). |
