To simplify \( 6^{-2} \), we can use the property of exponents that states \( a^{-n} = \frac{1}{a^n} \). Therefore:
\[ 6^{-2} = \frac{1}{6^2} \]
Calculating \( 6^2 \):
\[ 6^2 = 36 \]
Thus, we have:
\[ 6^{-2} = \frac{1}{36} \]
Now, we can check the provided options:
- \( 36 \) - Not equivalent.
- \( \frac{1}{6^{-2}} \) - This is equivalent to \( 6^2 \), which is \( 36 \).
- \( \frac{1}{36} \) - Equivalent to \( 6^{-2} \).
- \( \frac{1}{2^6} \) - Not equivalent.
The correct answer is:
\(\frac{1}{36}\)
