**Geometric Mean of Three Numbers**

The **geometric mean of three numbers** is the cube root of the product of the three numbers.

For example, find the geometric mean of 2, 4, and 16.

First, we find the product of 2, 4 and 16, that is 2 \times 4 \times 16 = 128.

The geometric mean is just the cube root of their product which is
