A lot depends on how I interpret what you have written.  What I think you are "saying" is

   log to the base 5 of 4x.  
5

Is that what you meant?

That should help if you have the question written down and can see the relation.

A basic rule applying to logarithmic functions and their inverses, exponential functions, is that 

log (to the base b) of (base b)^x = x.  In other words, the log and exp functions cancel one another out and the result is simply x.

Apply that concept to the problem that you've presented.  Ask qu. if that's still unclear for you.

To answer my own question:  the result is 4x.  Hope you got that.  If not, it's back to the drawing board.
