Understanding Cube Roots

A cube root of a number \(x\) is a value \(y\) that, when cubed (multiplied by itself three times), equals \(x\). In mathematical terms, if \(y^3 = x\), then \(y\) is the cube root of \(x\). Every real number has exactly one real cube root.

Formula

The cube root of \(x\) is represented as ³√x. Mathematically, it's expressed as:

$$ y = \sqrt[3]{x} \Leftrightarrow y^3 = x $$

Examples

  • The cube root of 8 is 2, because \(2 \times 2 \times 2 = 8\).
  • The cube root of -27 is -3, because \((-3) \times (-3) \times (-3) = -27\).
  • The cube root of 125 is 5, because \(5 \times 5 \times 5 = 125\).

Cube roots are fundamental in various areas of mathematics, science, and engineering. They are used in geometry to find the side length of a cube given its volume, in physics, and in many engineering calculations.
