# How do you evaluate 7^2?

Mar 9, 2018

$49$

#### Explanation:

When a number or a variable has an exponent, it means that that number/variable is multiplied by itself, that many times.

So here we have ${7}^{2}$

This means that $7$ is multiplied by itself, one other time. So we could rewrite is as:

$7 \cdot 7$

From here we solve:

$7 \cdot 7$

$= 49$
