An exponent is the same as an index and tells us what a power is made up of.

$7\times 7\times 7\times 7\times 7={7}^{5}$

The powers of 7 are:7; 49;343; 2,401; 16,807.

They are written with exponents as:

$7}^{1};{7}^{2};{7}^{3},{7}^{4},{7}^{5$

The powers of 7 are:7; 49;343; 2,401; 16,807.

A short hand method of writing repeated multiplication of a number is to express it in exponent form.

For example.

$2\times 2={2}^{2}$ the 2 in $2}^{2$ is called the base and the 2 in the $2}^{2$ the exponent

also$2\times 2\times 2\times 2={2}^{4}$ and so on

$\Rightarrow =7\times 7\times 7\times 7\times 7={7}^{5}$ in exponential form

The base is the value of the number being multiplied, in this case 7

and the exponent is the number of times, the number is being multiplied. In this case 5.

For example.
