What is a Cube Root?

The cube root of a number is a value that, when multiplied by itself three times, gives the original number.

For example:

  • The cube root of $8$ is $2$ because $2 \times 2 \times 2 = 8$
  • The cube root of $-27$ is $-3$ because $(-3) \times (-3) \times (-3) = -27$

In general:

  • If $x^3 = y$, then $x = \sqrt[3]{y}$

Cube Root Formula

The standard formula for cube root is:

$ \sqrt[3]{x} $

Where:

  • $x$ is the number
  • $\sqrt[3]{x}$ is the cube root of $x$

Examples of Cube Roots

  1. $ \sqrt[3]{125} = 5 $ because $5 \times 5 \times 5 = 125$
  2. $ \sqrt[3]{64} = 4 $ because $4 \times 4 \times 4 = 64$
  3. $ \sqrt[3]{-8} = -2 $ because $(-2) \times (-2) \times (-2) = -8$

Properties of Cube Roots

  • The cube root of a positive number is positive.
  • The cube root of a negative number is negative.
  • Every real number has exactly one real cube root.
