What Are Powers?

A power consists of a base and an exponent, and is used to write multiplication in an easier way. If you multiply a number by itself multiple times, it can be written as a power.

Theory

Powers

A power is an expression

ab = a × a × × a b times,

where a is the called the base, and b is the exponent.

The base a is the number that you multiply by itself, and b is how many times you are multiplying by a.

Example 1

Write 3 multiplied by itself 4 times as a power

3 × 3 × 3 × 3 = 34

Example 2

Write the number 25 as a power with 5 as a base

25 = 5 × 5 = 52

Note! If the exponent is equal to 0, the power is always 1, for all bases apart from 0.

Example 3

Power

Calculate 50 and 1000

50 = 1 1000 = 1
