 Cube root

For a real number $x$, its cube root is the unique real number $y$ satisfying $y^3=x$. The function $y\mapsto y^3$ is strictly increasing, so negative inputs also have a unique real cube root.

The cube root of a number \( x \) is a value \( y \) such that when \( y \) is multiplied by itself three times (i.e., \( y \times y \times y \)), the result equals \( x \).
