Exponents review

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 $\goldD{\text{exponent}}$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 $\blueD{\text{base}}$start color #11accd, start text, b, a, s, e, end text, end color #11accd. In this example, the base is $\blueD4$start color #11accd, 4, end color #11accd, and the exponent is $\goldD3$start color #e07d10, 3, end color #e07d10.

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

In our example, $\blueD4^\goldD3$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 $\blueD4$start color #11accd, 4, end color #11accd by itself $\goldD3$start color #e07d10, 3, end color #e07d10 times:

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

For example, $7^0=1$7, start superscript, 0, end superscript, equals, 1.
