Rewrite these powers as a fraction with a positive exponent.

Given:
The expression in negative exponents is given.
Required:
Write these powers as a fraction with a positive exponent.
Explanation:
Use the exponent property
[tex]a^{-m}=\frac{1}{a^m}[/tex](a)
[tex]5^{-3}=\frac{1}{5^3}[/tex](b)
[tex]m^{-6}=\frac{1}{m^6}[/tex](c)
[tex](xy)^{-4}=\frac{1}{(xy)^4}[/tex](d)
[tex]\begin{gathered} (-b)^{-2}=\frac{1}{(-b)^2} \\ =\frac{1}{(-1)^2(b)^2} \\ =\frac{1}{b^2} \end{gathered}[/tex]Final Answer:
