Question

geometric mean of 4 and 18.

Answer 1

Given:

4 and 18

To find:

The geometric mean of a and b

Solution:

Geometric mean of any number is defined as the nth root of the product of n numbers.

We have just two numbers that is:

• 4 and 18

So we have to find the square root of the product of 4 and 18

• $\sqrt{4.18}$
• $6\sqrt{2}$

Hence the geometric mean of 4 and 18 is $6\sqrt{2}$
