# Definition of Geometric Mean

The **geometric mean** of \(n\) numbers is equal to the \(n\)th root of the product of the numbers. It is a special type of average.

The geometric mean of two numbers is the square root of their product, the geometric mean of three numbers is the cube root of their product, and so on.

For example, the geometric mean of \(3\) and \(12\) is equal to \(\sqrt{(3 \times 12)} = \sqrt{36} = 6\).
