Cube root definition


∛(x) = y <=> y^3 = x

A cube root is a special case of exponent. It can be written down as

∛(x) = x ^ (1/3)

Most often, the cube root will not be a rational number (one that can be expressed as a quotient of two natural numbers).

You can also use this calculator to find the root of a higher degree. Go into the advanced mode and change the degree of the root. Our calculator will automatically do all necessary calculations. If you want to perform a reverse operation, head to the exponent calculator.


Cube root function

You can graph the function y = ∛(x). It is an odd function - it means that it is symmetric with respect to the origin and fulfills the condition - f(x) = f(-x). This function passes through zero.
