Ok, I have an Expression which is attached and it needs simplifying.
What I have done is got 12logx
But I dont think this is correct.
Another possible place I got to is logx4/logx1/3
Which one is it?

Show your work, ok? One of those is correct and one isn't. The trouble is that the one that is correct isn't very 'simplified'.

Ok, that's the correct one. But now use log(x^b)=b*log(x). What do you get? log(x)/log(x) isn't log(x).

Ok so, 4logx/1/3logx
Would the answer be just 12?
