To simplify the expression \(15^{-7} \cdot 29^{-5}\) using the Property of Negative Integer Exponents, we can rewrite it as follows:
\[ 15^{-7} = \frac{1}{15^7} \quad \text{and} \quad 29^{-5} = \frac{1}{29^5} \]
Thus,
\[ 15^{-7} \cdot 29^{-5} = \frac{1}{15^7} \cdot \frac{1}{29^5} = \frac{1}{15^7 \cdot 29^5} \]
This means we can write it as:
\[ \frac{1}{15^7 \cdot 29^5} = \frac{1}{15^7 \cdot 29^5} \quad \text{or} \quad \frac{1}{15^7 \cdot 29^5} \]
Looking at the options you provided:
- \( \frac{29^5}{15^7} \) (not equivalent)
- \( \frac{15^7}{29^5} \) (not equivalent)
- \( \frac{1}{15^7 \cdot 29^5} \) (this is equivalent)
- \( 15 \cdot 29^{15} \) (not equivalent)
The equivalent expression is:
\[ \frac{1}{15^7 \cdot 29^5} \]
So the correct answer is:
\( \frac{1}{15^7 \cdot 29^5} \).
