Answer 1

To solve the expression \( 25 \cdot 2^{-2} \), we need to evaluate \( 2^{-2} \) first.

The term \( 2^{-2} \) can be calculated as:

\[
2^{-2} = \frac{1}{2^2} = \frac{1}{4}
\]

Now we can substitute this back into the expression:

\[
25 \cdot 2^{-2} = 25 \cdot \frac{1}{4}
\]

To multiply this out:

\[
25 \cdot \frac{1}{4} = \frac{25}{4} = 6.25
\]

It seems we might not have an exact matching option in your responses based on a misunderstanding of what might be needed. However, if those options are:

- 8
- 16
- 2
- 128

None of these correspond to the correct result of \( 6.25 \). Please check the options again or clarify the operation if needed.
