Problem: Geometric mean {{61,64,67,70,73},{5,18,42,27,8}} [ Calculator, Method and examples ]

Solution:
Your problem -> Geometric mean {{61,64,67,70,73},{5,18,42,27,8}}

Geometric mean :
 x f flog(x) 61 5 20.5544 64 18 74.8599 67 42 176.5971 70 27 114.7094 73 8 34.3237 --- --- --- -- n=100 sum flog(x)=421.0444

GM of X = Antilog((sum flog(x))/n)

= Antilog((421.0444)/(100))

= Antilog(4.2104)

= 67.3865
