Cube root

The cube root of a number is a value that, when cubed, equals that number. It is the inverse operation of cubing.

Exponentiation: Exponentiation is the operation of raising a base to a power. Cubing is exponentiation with exponent three, which cube roots reverse.
Cubing: Cubing is raising a number to the third power. Cube roots undo cubing: cubing the root returns the original number.
Volume: Volume measures the three-dimensional space occupied by a solid. For a cube, taking the cube root of volume gives its side length.
Square root: A square root of a number is a value whose square equals that number. Unlike real cube roots, negative real numbers have no real square roots.
Integer: An integer is a whole number, its negative, or zero. Integer inputs can have exact integer cube roots, including negative roots.
Odd function: An odd function satisfies f(−x) = −f(x) wherever it is defined. The cube-root function preserves signs because cubing is odd.
Cube: A cube is a three-dimensional solid with six equal square faces. A cube’s edge length is the cube root of its volume.
Nth root: An nth root of a number is a value that raised to the nth power equals that number. Cube roots are the specific case of nth roots with n equal to three.
Real number: A real number is a value on the continuous number line. Every real number has exactly one real cube root.
Newton's method: Newton's method is an iterative procedure for approximating roots of equations. Applied to x³ − a = 0, it rapidly approximates the cube root of a.
