# Exponents review

Review the basics of exponents and try some practice problems.

## Exponents and bases

Here's what an exponent and a base look like:

The small number written above and to the right of a number is called an start color #e07d10, start text, e, x, p, o, n, e, n, t, end text, end color #e07d10. The number underneath the exponent is called the start color #11accd, start text, b, a, s, e, end text, end color #11accd. In this example, the base is start color #11accd, 4, end color #11accd, and the exponent is start color #e07d10, 3, end color #e07d10.

## Evaluating exponents

An exponent tells us to multiply the base by itself that number of times.

In our example, start color #11accd, 4, end color #11accd, start superscript, start color #e07d10, 3, end color #e07d10, end superscript tells us to multiply the base of start color #11accd, 4, end color #11accd by itself start color #e07d10, 3, end color #e07d10 times:

### What about when the exponent is a zero?

Any base with an exponent of zero is equal to 1.

For example, 7, start superscript, 0, end superscript, equals, 1.
