Question

What is the geometric mean of 5 and 7?

Answer 1

Geometric mean of 5 and 7 is 5.9161

Solution:

Given that,

We have to find the geometric mean of 5 and 7

The geometric mean of two numbers a and b is the square root of product of a and b

Which means,

$Geometric\ mean = \sqrt{ab}$

Geometric mean of 5 and 7

$Geometric\ mean = \sqrt{5 \times 7}\\\\Geometric\ mean = \sqrt{35}\\\\Geometric\ mean = 5.9161$

Thus geometric mean of 5 and 7 is 5.9161
