14^7/9^13

Answer 1

To rewrite the expression \( 14^{-7} / 9^{-13} \) using only positive exponents, we can apply the property of negative exponents, which states that \( a^{-n} = \frac{1}{a^n} \).

Starting with:

\[
\frac{14^{-7}}{9^{-13}}
\]

We can apply the negative exponent rule:

1. Rewrite \( 14^{-7} \) as \( \frac{1}{14^7} \).
2. Rewrite \( 9^{-13} \) as \( \frac{1}{9^{13}} \).

Thus:

\[
\frac{14^{-7}}{9^{-13}} = \frac{\frac{1}{14^7}}{\frac{1}{9^{13}}}
\]

When dividing by a fraction, it is equivalent to multiplying by the reciprocal:

\[
\frac{1}{14^7} \cdot \frac{9^{13}}{1} = \frac{9^{13}}{14^7}
\]

Therefore, an equivalent expression using only positive exponents is:

\[
\frac{9^{13}}{14^7}
\]

In the provided options, this corresponds to:

\[
\frac{9^{13}}{14^{7}}
\]

So the correct answer is:

\(\frac{9^{13}}{14^{7}}\)
