What is a Cube Root?
The cube root of a number is a value that, when multiplied by itself three times, gives the original number.
For example: ∛27 = 3 because 3 × 3 × 3 = 27.
Important Facts
- ∛0 = 0
- ∛1 = 1
- ∛8 = 2
- ∛27 = 3

Cube and Cube Root Relationship
If a³ = b, then ∛b = a.
Example: 7³ = 343, therefore ∛343 = 7.
Cube Root as an Exponent
A cube root can also be written using a fractional exponent:
∛x = x1/3
