I've recently finished the Basic Log Rules and those topics that are related to exponential and logarithms. The only question I've encountered is this:

For this log:

log_4^(16/x)

- log_4^(16) - log4^ (x)

I don't get how it'll become

log_4^(16) = 2

It says refer to the basic log but I still don't get it...

Is it because 4^2 = 16???

Thanks

Second question is what I've been doing is looking at numbers. What sort of exp/log questions in words will I encounter?
