Find the geometric mean between 3 and 12

Wanted the geometric mean between A = 3 and B = 12.

So the Geometric mean equation simply is √ (A * B).

Since A is 3 and B is 12 - >

= √ (3 * 12)

then plug in the equation - >

= √36

and the root of 36 = 6.

Therefore your answer is 6.

The answer would be 6
