cube roots
Third-power inverses
A cube root is a number that, when multiplied by itself three times, produces a given number.
The cube root of 8 is 2, because 2 × 2 × 2 = 8.
Every real number has exactly one real cube root, including negative numbers: the cube root of -27 is -3.
In notation, cube root uses a radical sign with a small 3: ∛64 = 4.
