Question

The geometric mean of 8 and 2 is ______.

4
3
16
5

Answer 1

   
$\displaystyle \\ m_g = \sqrt{8 \times 2 }= \sqrt{16}= \boxed{4}$

Answer 2

Answer: 4

Step-by-step explanation:

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

$GM=\sqrt{ab}$

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

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

$GM=\sqrt{8\times2}\\\\\Rightarrow\ GM=\sqrt{16}\\\\\Rightarrow\ 4$

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