## 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 $\goldD{\text{exponent}}$. The number underneath the exponent is called the $\blueD{\text{base}}$. In this example, the base is $\blueD4$, and the exponent is $\goldD3$.

## Evaluating exponents

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

In our example, $\blueD4^\goldD3$ tells us to multiply the base of $\blueD4$ by itself $\goldD3$ times:

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

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

For example, $7^0=1$.
