Rewrite these expressions then work out a numerical answer

Answer:
[tex]5^{-4} = \frac{1}{5^{4} } = \frac{1}{625}[/tex]
[tex]3^{-2} =\frac{1}{3^{2} } = \frac{1}{9}[/tex]
Step-by-step explanation:
You take the negative out of the exponent and move it down to the denominator.
Then, you find the answer to the denominator.
