Question

How do you simplify `9^(-1/2)` leaving only positive exponents?

Answer 1

`9^(-1/2)=1/9^(1/2)=1/3`

Explanation:

We have a 9 to the negative 1/2 power.

The power to 1/2 means we take the square root. The negative power means we'll have a positive power if we put it on the other side of the divide sign. Let's do this step by step to illustrate:

`9^(-1/2)=1/9^(1/2)=1/3`
