Evaluate: 5–^2 = <br> WILL MARK AS BRAINLIEST
Elanso [62]

When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.

For example:

x^{-2} or \frac{x^{-2}}{1}=\frac{1}{x^2}

\frac{1}{y^{-2}}=\frac{y^2}{1}  or  y²



So:

5^{-2}=\frac{1}{5^2}=\frac{1}{25}

Your answer is B
