Best ResponseYou've already chosen the best response.0how did you know what the variables were?

Mertsj

Best ResponseYou've already chosen the best response.1That is the property of law of logs. Perhaps your book uses different variables. What the variables are doesn't matter. Did you book say: \[m ^{n}=n \log_{10}m \]

Best ResponseYou've already chosen the best response.1So use that property on 3^x

Best ResponseYou've already chosen the best response.1This involves two laws of logs. On the left side you have the difference of two logs which is equal to the log of the quotient.
