Question

Evaluate the following expression.

3^-2

Evaluate the following expression.
5^-3

Answer 1

`3^-2 \\ \\ (1)/(3^2) \\ \\ (1)/(9) \\ \\ Answer: \fbox { 1/9 } \\ \\ ----- \\ \\ 5^-3 \\ \\ (1)/(5^3) \\ \\ (1)/(125) \\ \\ Answer: \fbox {1/125}`

Answer 2

`3^(-2) = (1)/(3^(2) ) = (1)/(9) \\ 5^(-3) = (1)/(5^(3) ) = (1)/(125)`

The answer to the first question is 1/9 and the answer to the second question is 1/125.

Hope this helps!
