Any chance of a hint?

Given that p>0 and q>0, show that

Log a (pq) = Log a (p) + Log a (q)

Just got a bit stuck so any help would be appreciated
You might want to start by thinking about what the log function actually is/does in comparison to other functions/operations that may be more familiar...
Start from ax+y=axaya^{x+y} = a^x a^y choosing suitable x,yx,y.
