Find Geometric mean {{61,5},{64,18},{67,42},{70,27},{73,8}}

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


`x``f``flog(x)`
615 20.5544 `20.5544=5 xx log(61)``=5 xx 4.1109`
6418 74.8599 `74.8599=18 xx log(64)``=18 xx 4.1589`
6742 176.5971 `176.5971=42 xx log(67)``=42 xx 4.2047`
7027 114.7094 `114.7094=27 xx log(70)``=27 xx 4.2485`
738 34.3237 `34.3237=8 xx log(73)``=8 xx 4.2905`
---------
--`n=100``sum flog(x)=421.0444`


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

`= Antilog((421.0444)/(100))`

`= Antilog(4.2104)`

`= 67.3865`
