The first step will be to combine the subtracted logs into one log containing a division, by applying the appropriate
log rule.
Once you have "log, base three, of (a rational expression)", convert this to the equivalent
exponential form, using the definition of logs: "three, to the power one, equals (a rational expression)".
Then
solve the resulting rational equation.

I'm afraid I don't know what they want you to do with a "base x" log...?

This one cannot be "solved", because it isn't an equation: this is no "equals" sign in this. Are you perhaps supposed to "evaluate"...?
