Help pls ;) <br> Find the geometric mean of 14 and 20

Kipish [7]

Answer:

The geometric mean of 14 and 20 is 16.73.

Step-by-step explanation:

It is required to find the geometric mean of 14 and 20. Let the numbers are :

a = 14 and b = 20

The geometric mean for two numbers is given by :

$M=\sqrt{ab}$

Plugging the values in above formula as follows :

$M=\sqrt{14\times 20}\\\\M=\sqrt{7\times 2\times 5\times 4} \\\\M=16.73$

So, the geometric mean of 14 and 20 is 16.73.
