## We'll cover the following

## What does “Power of a Number” mean?

The power (or **exponent**) $a$, of a number $x$ represents the number of times $x$ will be multiplied by itself. It is written as a small, superscript number to the right of and above the **base** number.

For example, if the base number is $2$ and the exponent value is $3$, we represent this as follows:

$2^3 = 8$
