Question

Find the geometric mean of sqrt 77 and sqrt 343.

Answer 1

Answer:

12.75

Step-by-step explanation:

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

As we know that

Geometric mean = $\sqrt{ab}$

where

a is the first number = $\sqrt{77}$

And, the b is the second number = $\sqrt{343}$

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

$= \sqrt{8.78 \times 18.52}$

= 12.75
