To rewrite the expression \( 6^{-2} \) using a single positive exponent, you can use the property of exponents that states \( a^{-n} = \frac{1}{a^n} \).
Thus, we have:
\[ 6^{-2} = \frac{1}{6^2} \]
Calculating \( 6^2 \):
\[ 6^2 = 36 \]
So,
\[ 6^{-2} = \frac{1}{36} \]
The expression \( 6^{-2} \) rewritten using a single, positive exponent is:
\[ \frac{1}{6^2} \]
And you can also refer to it as:
\[ \frac{1}{36} \]
