Definition of Power

Definition of Power

The power of a number tells us how many times we need to multiply it with itself to give the required value.

It is written as a little number above and to the right of the base number.

For example, \(9^4 = 9 \times 9 \times 9 \times 9\). The power of \(4\) tells us to multiply \(9\) by itself \(4\) times.

Other terms for "power" are "index" and "exponent".
