Question

Rewrite these powers as a fraction with a positive exponent.

Answer 1

Given:

The expression in negative exponents is given.

Required:

Write these powers as a fraction with a positive exponent.

Step-by-step explanation:

Use the exponent property

`a^(-m)=(1)/(a^m)`

(a)

`5^(-3)=(1)/(5^3)`

(b)

`m^(-6)=(1)/(m^6)`

(c)

`(xy)^(-4)=(1)/((xy)^4)`

(d)

`\begin{gathered} (-b)^(-2)=(1)/((-b)^2) \\ =(1)/((-1)^2(b)^2) \\ =(1)/(b^2) \end{gathered}`

Final Answer:
