# The Exponent of a Number

In this lesson, we will learn how to find the exponent of a number using recursion.

## What does Exponent of a Number mean?

An exponent tells you how many times the base number is used as a factor. It is written as a small number to the right of and above the base number. A base of five raised to the *second power* is called **five squared**. This means **five times five**. Five raised to the *third power* is called **five cubed**. It means **five times five times five**. The base can be any sort of number; a whole number, a decimal number, or a fraction can all be raised to a power.

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

$ 2^3 = 8 $

The following illustration explains the concept.
