The geometric mean of 10 and 20 is 14.1421356237
it is 10
It is sqrt(20) = 4.4721, approx.
√15 x √20 = 3.87298334620742 x 4.47213595499958 = 17.3205080756888
√12 x √20 = 3.46410161513775 x 4.47213595499958 = 15.4919333848297
Geometric mean of 6 and 20 = sqrt(6*20) = sqrt(120) = 10.95445
Used the GEOMEAN function on Excel and the answer it gave was 20.
Geometric mean = sqrt(5*80) = sqrt(400) = 20
22.36068
34.6410161514
Geometric mean of two numbers is the square root of their product so sqrt(8*50) = sqrt(400) = 20
