The problem in the image asks to rewrite the expression \( \frac{1}{n^{-2}} \) using a positive exponent and then simplify.

### Step-by-Step Solution:

1. The expression given is: 

   \[
   \frac{1}{n^{-2}}
   \]

2. To convert the negative exponent into a positive exponent, apply the property of exponents: 

   \[
   \frac{1}{n^{-a}} = n^{a}
   \]

3. Therefore, applying this property:

   \[
   \frac{1}{n^{-2}} = n^{2}
   \]

Thus, the simplified expression with positive exponents is:

\[
n^2
\]
