Roots

We already know that a number multiplied by itself more than three times is called a power (refer to Powers)
The roots works the other way: where you have the resulting power, and you want to find the number that is multiplied by itself for a number of times to get the power

Power 24 = 2 × 2 × 2 × 2 = 16
Roots 4√16 = 2
Root can also
be written as
16¼ = 2

• Examples

  Root Power
1.  4√16 = 2 2 × 2 × 2 × 2 = 16
2. 4√81 = 3 3 × 3 × 3 × 3 = 81
3. 321/5 = 2 2 × 2 × 2 × 2 × 2 = 32
4. 2431/5 = 3 3 × 3 × 3 × 3 × 3 = 243
