Cube-root

A number that, when multiplied by itself three times, gives the original number. The cube root of 27 is 3 because 3 × 3 × 3 = 27, written as ∛27 = 3.

Combines 'cube' (from Greek 'kybos' meaning die or cube) with 'root.' The concept emerged from geometric problems involving cubes and volumes, with systematic study developing alongside algebra. The cube root symbol ∛ evolved as an extension of the square root symbol.
