金声玉亮2.0 To find the determinant of the given matrix:

\[
\left(
\begin{array}{cc}
\frac{34}{15} & \frac{2}{5} \\
\frac{47}{15} & \frac{53}{15} \\
\end{array}
\right)
\]

we use the formula for the determinant of a 2x2 matrix:

\[
\text{det} = ad - bc
\]

where the matrix is:

\[
\left(
\begin{array}{cc}
a & b \\
c & d \\
\end{array}
\right)
\]

For the given matrix:

\[
a = \frac{34}{15}, \quad b = \frac{2}{5}, \quad c = \frac{47}{15}, \quad d = \frac{53}{15}
\]

First, we calculate \( ad \):

\[
ad = \left(\frac{34}{15}\right) \left(\frac{53}{15}\right) = \frac{34 \times 53}{15 \times 15} = \frac{1802}{225}
\]

Next, we calculate \( bc \):

\[
bc = \left(\frac{2}{5}\right) \left(\frac{47}{15}\right) = \frac{2 \times 47}{5 \times 15} = \frac{94}{75}
\]

To subtract these fractions, we need a common denominator. The common denominator for 225 and 75 is 225:

\[
\frac{94}{75} = \frac{94 \times 3}{75 \times 3} = \frac{282}{225}
\]

Now, we can subtract:

\[
ad - bc = \frac{1802}{225} - \frac{282}{225} = \frac{1802 - 282}{225} = \frac{1520}{225} \approx 6.8
\]

Thus, the determinant of the matrix is:

\[
\boxed{6.8}
\]

To find the determinant of the matrix

\[
\begin{pmatrix}
\frac{34}{15} & \frac{2}{5} \\
\frac{47}{15} & \frac{53}{15} \\
\end{pmatrix},
\]

we use the formula for the determinant of a 2x2 matrix \(\begin{pmatrix} a & b \\ c & d \end{pmatrix}\), which is \(ad - bc\).

First, compute the product of the elements on the main diagonal:

\[
\frac{34}{15} \times \frac{53}{15} = \frac{34 \times 53}{15 \times 15} = \frac{1802}{225}.
\]

Next, compute the product of the off-diagonal elements:

\[
\frac{2}{5} \times \frac{47}{15} = \frac{2 \times 47}{5 \times 15} = \frac{94}{75}.
\]

Convert \(\frac{94}{75}\) to a fraction with the same denominator as \(\frac{1802}{225}\):

\[
\frac{94}{75} = \frac{94 \times 3}{75 \times 3} = \frac{282}{225}.
\]

Subtract the two fractions:

\[
\frac{1802}{225} - \frac{282}{225} = \frac{1802 - 282}{225} = \frac{1520}{225}.
\]

Simplify the resulting fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5:

\[
\frac{1520}{225} = \frac{1520 \div 5}{225 \div 5} = \frac{304}{45}.
\]

Thus, the determinant of the matrix is

\[
\boxed{\dfrac{304}{45}}.

gpto1 To find the determinant of the 2x2 matrix:

\[
\begin{pmatrix}
\frac{34}{15} & \frac{2}{5} \\
\frac{47}{15} & \frac{53}{15}
\end{pmatrix}
\]

We use the formula for the determinant of a 2x2 matrix:

\[
\text{det} =
\begin{vmatrix}
a & b \\
c & d \\
\end{vmatrix}
= ad - bc
\]

First, compute the products in the determinant formula:

\[
\begin{align*}
ad &= \left( \frac{34}{15} \right) \left( \frac{53}{15} \right) = \frac{34 \times 53}{15 \times 15} = \frac{1802}{225} \\
bc &= \left( \frac{2}{5} \right) \left( \frac{47}{15} \right) = \frac{2 \times 47}{5 \times 15} = \frac{94}{75} = \frac{282}{225} \quad (\text{after adjusting denominator to 225})
\end{align*}
\]

Next, subtract \( bc \) from \( ad \):

\[
\text{det} = \frac{1802}{225} - \frac{282}{225} = \frac{1802 - 282}{225} = \frac{1520}{225}
\]

Simplify the fraction by dividing numerator and denominator by their greatest common divisor (GCD), which is 5:

\[
\frac{1520}{225} = \frac{1520 \div 5}{225 \div 5} = \frac{304}{45}
\]

Thus, the determinant of the matrix is:

\[
\boxed{\dfrac{304}{45}}
\]

gpt-4o-2024-08-06 To find the determinant of a \(2 \times 2\) matrix

\[
\begin{pmatrix}
a & b \\
c & d
\end{pmatrix},
\]

we use the formula:

\[
\text{det} = ad - bc.
\]

For the given matrix

\[
\begin{pmatrix}
\frac{34}{15} & \frac{2}{5} \\
\frac{47}{15} & \frac{53}{15}
\end{pmatrix},
\]

we identify \(a = \frac{34}{15}\), \(b = \frac{2}{5}\), \(c = \frac{47}{15}\), and \(d = \frac{53}{15}\).

First, calculate \(ad\):

\[
ad = \left(\frac{34}{15}\right) \left(\frac{53}{15}\right) = \frac{34 \times 53}{15 \times 15}.
\]

Calculate \(34 \times 53\):

\[
34 \times 53 = 34 \times (50 + 3) = 34 \times 50 + 34 \times 3 = 1700 + 102 = 1802.
\]

Thus,

\[
ad = \frac{1802}{225}.
\]

Next, calculate \(bc\):

\[
bc = \left(\frac{2}{5}\right) \left(\frac{47}{15}\right) = \frac{2 \times 47}{5 \times 15}.
\]

Calculate \(2 \times 47\):

\[
2 \times 47 = 94.
\]

Thus,

\[
bc = \frac{94}{75}.
\]

Now, find the determinant:

\[
\text{det} = ad - bc = \frac{1802}{225} - \frac{94}{75}.
\]

To subtract these fractions, find a common denominator. The least common multiple of 225 and 75 is 225. Convert \(\frac{94}{75}\) to a fraction with denominator 225:

\[
\frac{94}{75} = \frac{94 \times 3}{75 \times 3} = \frac{282}{225}.
\]

Now subtract:

\[
\text{det} = \frac{1802}{225} - \frac{282}{225} = \frac{1802 - 282}{225} = \frac{1520}{225}.
\]

Simplify \(\frac{1520}{225}\). The greatest common divisor of 1520 and 225 is 5.

Divide both the numerator and the denominator by 5:

\[
\frac{1520}{225} = \frac{1520 \div 5}{225 \div 5} = \frac{304}{45}.
\]

Thus, the determinant of the matrix is

\[
\boxed{\frac{304}{45}}.

DeepSeek-Coder-V2-Lite-Instruct To find the determinant of the given 2x2 matrix, we use the formula for the determinant of a 2x2 matrix \(\left(\begin{array}{cc} a & b \\ c & d \end{array}\right)\), which is \(ad - bc\).

Given matrix:
\[
\left(\begin{array}{cc}
\frac{34}{15} & \frac{2}{5} \\
\frac{47}{15} & \frac{53}{15} \\

ad = \left(\frac{34}{15}\right) \left(\frac{53}{15}\right) = \frac{34 \times 53}{15 \times 15} = \frac{1802}{225}
\]

2. Calculate \(bc\):
\[
bc = \left(\frac{2}{5}\right) \left(\frac{47}{15}\right) = \frac{2 \times 47}{5 \times 15} = \frac{94}{75}
\]

3. Subtract \(bc\) from \(ad\):
\[
\text{Determinant} = ad - bc = \frac{1802}{225} - \frac{94}{75}
\]

4. To subtract these fractions, we need a common denominator. The least common multiple of 225 and 75 is 225. Convert \(\frac{94}{75}\) to a fraction with a denominator of 225:
\[

\]

5. Now subtract the fractions:
\[
\text{Determinant} = \frac{1802}{225} - \frac{282}{225} = \frac{1802 - 282}{225} = \frac{1520}{225}
\]

6. Simplify the fraction \(\frac{1520}{225}\):
\[
\frac{1520}{225} = \frac{304}{45}

Qwen2-72B-Instruct To find the determinant of a 2x2 matrix, you can use the formula:

$$\text{det}(A) = ad - bc$$

where $A = \left( \begin{array}{cc} a & b \\ c & d \end{array} \right)$.

Given the matrix $A = \left( \begin{array}{cc} \frac{34}{15} & \frac{2}{5} \\ \frac{47}{15} & \frac{53}{15} \end{array} \right)$,

we have $a = \frac{34}{15}$, $b = \frac{2}{5}$, $c = \frac{47}{15}$, and $d = \frac{53}{15}$.

Substituting these values into the formula gives:

$$\text{det}(A) = \left(\frac{34}{15}\right)\left(\frac{53}{15}\right) - \left(\frac{2}{5}\right)\left(\frac{47}{15}\right)$$

Simplifying this expression:

$$\text{det}(A) = \frac{1802}{225} - \frac{94}{75} = \frac{1802}{225} - \frac{188}{225} = \frac{1614}{225} = \frac{538}{75}$$

Therefore, the determinant of the given matrix is $\boxed{\frac{538}{75}}$.

baichuan4 To find the determinant of a $2 \times 2$ matrix, we use the formula:

$$\text{det}\left(\begin{array}{cc}
a & b \\
c & d \\
\end{array}\right) = ad - bc$$

Given the matrix:

$$\left(\begin{array}{cc}
\frac{34}{15} & \frac{2}{5} \\
\frac{47}{15} & \frac{53}{15} \\
\end{array}\right)$$

We can identify the elements as:

$$a = \frac{34}{15}, \quad b = \frac{2}{5}, \quad c = \frac{47}{15}, \quad d = \frac{53}{15}$$

Now, we calculate the determinant:

$$\text{det} = \left(\frac{34}{15}\right)\left(\frac{53}{15}\right) - \left(\frac{2}{5}\right)\left(\frac{47}{15}\right)$$

First, we multiply the diagonal elements:

$$\left(\frac{34}{15}\right)\left(\frac{53}{15}\right) = \frac{34 \cdot 53}{15 \cdot 15} = \frac{1802}{225}$$

Then, we multiply the off-diagonal elements:

$$\left(\frac{2}{5}\right)\left(\frac{47}{15}\right) = \frac{2 \cdot 47}{5 \cdot 15} = \frac{94}{75}$$

Now, we subtract these two products:

$$\text{det} = \frac{1802}{225} - \frac{94}{75}$$

In order to subtract these fractions, we need to find a common denominator. We can see that $225$ is $3$ times $75$, so we multiply the second fraction by $\frac{3}{3}$ to get the same denominator:

$$\text{det} = \frac{1802}{225} - \frac{94 \cdot 3}{75 \cdot 3} = \frac{1802}{225} - \frac{282}{225}$$

Now, we can subtract the numerators:

$$\text{det} = \frac{1802 - 282}{225} = \frac{1520}{225}$$

This fraction can be simplified by dividing both the numerator and denominator by $15$:

$$\text{det} = \frac{1520 \div 15}{225 \div 15} = \frac{101 \cdot 15}{15 \cdot 15} = \frac{101}{15}$$

Therefore, the determinant of the given matrix is:

$$\boxed{\frac{101}{15}}$$

=&\frac{20}{3}
\end{align*}

gpto1 To find the determinant of the 2x2 matrix:

\[
\begin{pmatrix}
\frac{34}{15} & \frac{2}{5} \\
\frac{47}{15} & \frac{53}{15}
\end{pmatrix}
\]

We use the formula for the determinant of a 2x2 matrix:

\[
\text{det} =
\begin{vmatrix}
a & b \\
c & d \\
\end{vmatrix}
= ad - bc
\]

First, compute the products in the determinant formula:

\[
\begin{align*}
ad &= \left( \frac{34}{15} \right) \left( \frac{53}{15} \right) = \frac{34 \times 53}{15 \times 15} = \frac{1802}{225} \\
bc &= \left( \frac{2}{5} \right) \left( \frac{47}{15} \right) = \frac{2 \times 47}{5 \times 15} = \frac{94}{75} = \frac{282}{225} \quad (\text{after adjusting denominator to 225})
\end{align*}
\]

Next, subtract \( bc \) from \( ad \):

\[
\text{det} = \frac{1802}{225} - \frac{282}{225} = \frac{1802 - 282}{225} = \frac{1520}{225}
\]

Simplify the fraction by dividing numerator and denominator by their greatest common divisor (GCD), which is 5:

\[
\frac{1520}{225} = \frac{1520 \div 5}{225 \div 5} = \frac{304}{45}
\]

Thus, the determinant of the matrix is:

\[
\boxed{\dfrac{304}{45}}

\frac{304}{45}
kimi To find the determinant of the given 2x2 matrix, we will use the formula for the determinant of a 2x2 matrix:

\[
\text{det}\left(\begin{array}{cc}
a & b \\
c & d \\
\end{array}\right) = ad - bc
\]

Given the matrix:

\[
\left(\begin{array}{cc}
\frac{34}{15} & \frac{2}{5} \\
\frac{47}{15} & \frac{53}{15} \\
\end{array}\right)
\]

We identify the elements as follows:
- \( a = \frac{34}{15} \)
- \( b = \frac{2}{5} \)
- \( c = \frac{47}{15} \)
- \( d = \frac{53}{15} \)

Now, we substitute these values into the determinant formula:

\[
\text{det} = \left(\frac{34}{15}\right) \left(\frac{53}{15}\right) - \left(\frac{2}{5}\right) \left(\frac{47}{15}\right)
\]

First, calculate \( ad \):

\[
ad = \left(\frac{34}{15}\right) \left(\frac{53}{15}\right) = \frac{34 \times 53}{15 \times 15} = \frac{1802}{225}
\]

Next, calculate \( bc \):

\[
bc = \left(\frac{2}{5}\right) \left(\frac{47}{15}\right) = \frac{2 \times 47}{5 \times 15} = \frac{94}{75}
\]

To subtract these fractions, we need a common denominator. The least common multiple of 225 and 75 is 225. Convert \( \frac{94}{75} \) to a fraction with a denominator of 225:

\[
\frac{94}{75} = \frac{94 \times 3}{75 \times 3} = \frac{282}{225}
\]

Now, subtract the fractions:

\[
\text{det} = \frac{1802}{225} - \frac{282}{225} = \frac{1802 - 282}{225} = \frac{1520}{225}
\]

Simplify the fraction by finding the greatest common divisor (GCD) of 1520 and 225. The GCD is 5.

\[
\frac{1520 \div 5}{225 \div 5} = \frac{304}{45}
\]

Thus, the determinant of the matrix is:

\[
\boxed{\frac{304}{45}}

wenxinyiyan To find the determinant of a 2x2 matrix, we use the formula:

$$\text{Determinant} = (a \times d) - (b \times c)$$

For the given matrix:

$$\left(
\begin{array}{cc}
\frac{34}{15} & \frac{2}{5} \\\
\frac{47}{15} & \frac{53}{15} \\\
\end{array}
\right)$$

We have:

$a = \frac{34}{15}$
$b = \frac{2}{5}$
$c = \frac{47}{15}$
$d = \frac{53}{15}$

Plugging these values into the determinant formula, we get:

$$\text{Determinant} = \left(\frac{34}{15} \times \frac{53}{15}\right) - \left(\frac{2}{5} \times \frac{47}{15}\right)$$

$$\text{Determinant} = \frac{1802}{225} - \frac{94}{75}$$

To subtract these fractions, we find a common denominator:

$$\text{Determinant} = \frac{1802}{225} - \frac{282}{225}$$

$$\text{Determinant} = \frac{1520}{225}$$

Simplifying this fraction, we get:

$$\text{Determinant} = \frac{304}{45}$$

So, the determinant of the given matrix is $\boxed{\frac{304}{45}}$.

ad = \left(\frac{34}{15}\right) \left(\frac{53}{15}\right) = \frac{34 \times 53}{15 \times 15} = \frac{1802}{225}
\]

Next, compute \(bc\):

\[
bc = \left(\frac{2}{5}\right) \left(\frac{47}{15}\right) = \frac{2 \times 47}{5 \times 15} = \frac{94}{75}
\]

To subtract these fractions, we need a common denominator. The common denominator of 225 and 75 is 225. Convert \(\frac{94}{75}\) to a fraction with a denominator of 225:

\[
\frac{94}{75} = \frac{94 \times 3}{75 \times 3} = \frac{282}{225}
\]

Now, subtract \(bc\) from \(ad\):

\[
ad - bc = \frac{1802}{225} - \frac{282}{225} = \frac{1802 - 282}{225} = \frac{1520}{225}
\]

Simplify \(\frac{1520}{225}\):

\[
\frac{1520}{225} = \frac{1520 \div 5}{225 \div 5} = \frac{304}{45}
\]

Further simplify \(\frac{304}{45}\):

\[
\frac{304}{45} = \frac{304 \div 1}{45 \div 1} = \frac{304}{45}
\]

Since 304 and 45 have no common factors other than 1, \(\frac{304}{45}\) is in its simplest form.

Thus, the determinant of the matrix is:

\[
\boxed{\frac{304}{45}}
\]

deepseek-v3 To find the determinant of the given \( 2 \times 2 \) matrix:

\[
\left(\begin{array}{cc}
\frac{34}{15} & \frac{2}{5} \\
\frac{47}{15} & \frac{53}{15} \\
\end{array}\right)
\]

we use the formula for the determinant of a \( 2 \times 2 \) matrix:

\[
\text{det} = ad - bc
\]

where the matrix is:

\[
\left(\begin{array}{cc}
a & b \\
c & d \\
\end{array}\right)
\]

**Step 1: Identify the elements of the matrix.**

\[
a = \frac{34}{15}, \quad b = \frac{2}{5}, \quad c = \frac{47}{15}, \quad d = \frac{53}{15}
\]

**Step 2: Apply the determinant formula.**

\[
\text{det} = \left(\frac{34}{15} \times \frac{53}{15}\right) - \left(\frac{2}{5} \times \frac{47}{15}\right)
\]

**Step 3: Calculate each product separately.**

\[
\frac{34}{15} \times \frac{53}{15} = \frac{34 \times 53}{15 \times 15} = \frac{1802}{225}
\]

\[
\frac{2}{5} \times \frac{47}{15} = \frac{2 \times 47}{5 \times 15} = \frac{94}{75}
\]

**Step 4: Express both fractions with a common denominator.**

The least common denominator (LCD) of 225 and 75 is 225.

\[
\frac{94}{75} = \frac{94 \times 3}{75 \times 3} = \frac{282}{225}
\]

**Step 5: Subtract the two fractions.**

\[
\text{det} = \frac{1802}{225} - \frac{282}{225} = \frac{1802 - 282}{225} = \frac{1520}{225}
\]

**Step 6: Simplify the fraction.**

Divide the numerator and the denominator by their greatest common divisor (GCD). The GCD of 1520 and 225 is 5.

\[
\frac{1520 \div 5}{225 \div 5} = \frac{304}{45}
\]

**Final Answer:**

\[
\boxed{\dfrac{304}{45}}
\]
\frac{304}{45}
