LOGARITHMS 2




If Logay = Loga6 +  Loga3 ; find y.

solution

Logay = Loga6 +  Loga3

Logay = Loga(6 x 3)         [since Logam +  Logan = Loga(m x n)]  

Logay = Loga18

Hence y = 18                  [since Loga cancels out]

TRY THIS..............................

If Logax = Loga5 +  Loga60 ; find x.
