Cube Roots

We already know that a number multiplied by itself three times is called a cube (refer to Cubes)
The cube root works the other way: where you have the resulting cube, and you want to find the number that is multiplied by itself three times to get the cube

Cube 33 = 3 × 3 × 3 = 27
Cube root 3√27 = 3
Cube root can also
be written as
271/3 = 3

• Examples

Cube root Cube
1. 3√8 = 2 23 = 2 × 2 × 2 = 8
2. 3√27 = 3 33 = 3 × 3 × 3 = 27
3. 3√64 = 4 43 = 4 × 4 × 4 = 64
4. 3√125 = 5 53 = 5 × 5 × 5 = 125
