Question

Find the geometric mean of 5, 7, 0, 10 and 8.​

Answer 1

The answer is 6 as

5+0+710+8/5

=6

Answer 2

The geometric mean of 5, 7, 0, 10 and 8. is 0.

First of all let us understand what does geometric mean means.

Let there be 'n' number of numbers. They are:

a1 + a2 + a3 + ..... an. Then GM (geometric mean) is:

GM = $\sqrt[n]{a1 * a2 * a3 * .... * an}$

Here, the numbers are 5,7,0,10,8. They are 5 in total. So,

GM = $\sqrt[5]{5*7*0*10*8}$

= 0

Thus, geometric mean is equal to 0.
