To determine the exponent of \(109\) in the prime factorization of \(x^{11}\), start with the given factorization of \(x = 107 \cdot 109^5\). Raising \(x\) to the 11th power:

\[
x^{11} = \left(107 \cdot 109^5\right)^{11} = 107^{11} \cdot \left(109^5\right)^{11}.
\]

Applying the exponentiation rule \((a^m)^n = a^{m \cdot n}\), the exponent of \(109\) becomes:

\[
\left(109^5\right)^{11} = 109^{5 \times 11} = 109^{55}.
\]

Thus, the exponent of \(109\) in \(x^{11}\) is \(55\).

GPT-4o To determine the exponent of \(109\) in the prime factorization of \(x^{11}\), we first consider the given information about \(x\). The number \(x\) factors as:
\[ x = 107 \cdot 109^5 \]

When raising \(x\) to the 11th power, we have:
\[ x^{11} = (107 \cdot 109^5)^{11} \]

According to the properties of exponents, we can distribute the exponent across the factors:
\[ x^{11} = 107^{11} \cdot (109^5)^{11} \]

Simplifying \( (109^5)^{11} \):
\[ (109^5)^{11} = 109^{5 \cdot 11} = 109^{55} \]

So, the exponent of \(109\) in the prime factorization of \(x^{11}\) is \(55\).

doubao When we raise $x$ to the power of 11, we multiply the exponents of each prime factor by 11. So the exponent of 109 in $x^{11}$ is $5\times11=55$.

So the answer is B.
B
minimax The exponent of $109$ in the prime factorization of $x$ is $5$. When we raise $x$ to the $11$th power, we raise the exponent of $109$ to the $11$th power as well. Therefore, the exponent of $109$ in the prime factorization of $x^{11}$ is $5 \times 11 = 55$.

Answer: B. 55

kimi To solve this problem, we first need to understand the prime factorization of the given number \( x \). The number \( x \) is given as \( 107 \cdot 109^5 \). This means that \( x \) has a prime factorization of \( 107^1 \cdot 109^5 \).

Now, we want to find the exponent of \( 109 \) in the prime factorization of \( x^{11} \). To do this, we raise each prime factor in the factorization of \( x \) to the power of 11:

\( (107^1 \cdot 109^5)^{11} = 107^{11} \cdot 109^{55} \)

So, when \( x \) is raised to the power of 11, the exponent of \( 109 \) in the prime factorization of \( x^{11} \) is \( 55 \).

Explanation:
Given that $x = 107 \cdot 109^{5}$, we can find $x^{11}$ by raising both factors to the power of 11:
$x^{11} = (107 \cdot 109^{5})^{11}$
$= 107^{11} \cdot (109^{5})^{11}$
$= 107^{11} \cdot 109^{55}$
From this prime factorization of $x^{11}$, we can see that the exponent of $109$ is 55.

zhipu To find the exponent of \(109\) in the prime factorization of \(x^{11}\), we start by examining the given factorization of \(x\):

\[ x = 107 \cdot 109^5 \]

We need to raise \(x\) to the power of \(11\):

\[ x^{11} = (107 \cdot 109^5)^{11} \]

Using the properties of exponents, we can distribute the exponent \(11\) to each factor:

\[ x^{11} = 107^{11} \cdot (109^5)^{11} \]

Now, simplify the expression for \((109^5)^{11}\):

\[ (109^5)^{11} = 109^{5 \cdot 11} = 109^{55} \]

Therefore, in the prime factorization of \(x^{11}\), the exponent of \(109\) is \(55\).

So, the correct answer is:
