Question

The geometric mean of 8 and 2 is ______.

4
3
16
5

Answer 1

`\displaystyle \\ m_g = √(8 * 2 )= √(16)= \boxed{4}`

Answer 2

Answer: 4

Explanation:

We know that the geometric mean of two numbers a and b is given by :-

`GM=√(ab)`

The given numbers are: a= 8 and b =2

Then the geometric mean of 8 and 2 is given by :-

`GM=√(8*2)\\\\\Rightarrow\ GM=√(16)\\\\\Rightarrow\ 4`

Hence, the geometric mean of 8 and 2 is 4.
