Question

given formula :

log(a) b = (log(x) b) /(log(x) a)

what mean that :

log(5) 9 = (log(3) 9)/(log(3) 5) =
= (log(3) 3^2)/(log(3) 5) =
=(2log(3) 3)/(log(3) 5) =
= 2log(3) (3-5) = 2log(3) (-2) = log(3) ((-2)^2) =
= log(3) 4

in this way this is solved right,correct ?

Answer 1

4th line should be......
2/log(3)5

and that's as far as you can go
