The root There is some confusion on the questioner's part. A root is a root.

Numbers have many roots:

The square root of 64 is 8 since 8 squared is 64: 8² = 8 × 8 = 64

The cube root of 64 is 4 since 4 cubed is 64: 4³ = 4 × 4 × 4 = 64

The square root of a number x is sometimes called "radical x" because x appear after the radical (or square root) symbol: √x

As square roots are used a lot, it is also often abbreviated from "square root" to just "root", for example √2 can be read as "root 2" though to be strictly correct it is "square root of 2".

Roots also refer to solutions to equations (linear, quadratics, cubics, or higher polynomials) where they equal 0, for example x = -3 and x = 2 are the roots of the equation x² + x - 6 = 0; x = -2, x = 1 and x = 4 are the roots of x³ - 3x² - 6x + 8 = 0.
