# How do you evaluate (-9)^3?

Jan 4, 2017

The answer to this is -729.

#### Explanation:

What you can do first to this question is find out what ${9}^{3}$ is.

The answer to that is 729.

Then, look at the exponent itself.

If the exponent is an even number, then the answer will always be positive; since a negative number $\times$ a negative number is equal to a positive one.

In this case, the exponent is odd and the number is negative, so the answer will be negative.
