Question

Could someone help me figure this out?

I need to find the geometric mean of 3 and 6.

Please explain to me how to do this and not just give me the answer.

Answer 1

The geometric mean of 3 and 6 is

3•6= 18
Sqrt (18)= sqrt (2•3•3)= 3 sqrt (2)

If you have to find the geometric mean of two numbers like 3 and 6,
think that 3 by 6 will give you a rectangle and the geometric mean will give you a square 3 sqrt (2) by 3 sqrt (3)
