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

What is the simplified expression for,

Nostrana [21]

Here are a few rules you need to know for this equation:

Multiplying exponents of the same base: $x^m\times x^n=x^{m+n}$
Dividing exponents of the same base: $\frac{x^m}{x^n}=x^{m-n}$
Turning a negative exponent to a positive one: $x^{-m}=\frac{1}{x^m};\frac{1}{x^{-m}}=x^m$
