**zee**, Wednesday, April 20, 2011 at 8:17amIf there is anything about log, it is logarithmic

So take the log of both sides,

log 300 = log 8y

Writing 300 as 3*100,

log(3*100)=log 8y

Using log(AB) = log A+log B,

log 3+log100=log 8+log y

Because log 100=2,

log 3+2=log 8+log y

Rearrange: log 8-log 3=log y-2

By log(A/B)=log A-log B,

log (8/3)=log y-2
