What Is A Cube Root?

A cube root is a number that, when multiplied by itself three times, gives the original value.

How To Simplify A Cube Root

  1. Find the largest perfect cube factor.
  2. Move that factor outside the radical.
  3. Leave the remaining factor inside.

Worked Example

The cube root of 54 simplifies to 3 ∛2 because 54 = 27 x 2.
