An exponent is a number that tells the number of times the base is used as a factor.

In 20^{3}, 3 is the exponent and 20 is the base. The exponent ( 3 ) tells us that the base ( 20 ) will be a factor 3 times.

20 × 20 × 20

**Other examples**

In 12^{9}, 9 is the exponent.

In 7^{-2}, -2 is the exponent.

In 5^{147}, 147 is the exponent.

A common mistake by students is to say that 6^{4} = 6 × 4.

6^{4} is not equal to 6 × 4.

It is equal to

6 × 6 × 6 × 6
