Cube root
A cube root of a number is some number which when multiplied twice by itself gives the original
3 number. The symbol used to denote a square root is √ .
3
For example, √8 = 2 because when 2 is multiplied by itself twice it results in the original number
(8).
REMEMBER:
All positive numbers have two square roots. 16 = (-4)2 = (4)2, so √16 = -4 or 4 The square and cube root of 0 is 0.
The square and cube root of 1 is 1.
Negative numbers don’t have a square or cube root.
