To find the numerical equivalent of \(25 \cdot 2^{-2}\), we first need to simplify \(2^{-2}\).
The expression \(2^{-2}\) means \(\frac{1}{2^2}\), which is \(\frac{1}{4}\).
Now we can calculate:
\[ 25 \cdot 2^{-2} = 25 \cdot \frac{1}{4} = \frac{25}{4} = 6.25 \]
None of the options provided (16, 2, 128, 8) are equivalent to 6.25. If you have any further questions or if there's another way to interpret the expression, feel free to ask!
