Question

Find the geometric mean of sqrt 77 and sqrt 343.

Answer 1

12.75

Explanation:

The computation of the geometric mean of sqrt 77 and sqrt 343 is given below:

As we know that

Geometric mean =
`√(ab)`

where

a is the first number =
`√(77)`

And, the b is the second number =
`√(343)`

Now first we have to convert into a number

For a it, is = 8.78

And, for b, it is = 18.52

Now the geometric mean is

`= √(8.78 * 18.52)`

= 12.75
