    Can you show some working? Obviously the first step is to take logarithms of both sides.

    also quick thing, you might want to emphasise if it is:
    1. (4^x)+2=5^x
    or 2. 4^(x+2)=5^x

    It will be version (2) but, you're right, the question is ambiguous.

    Please don't post full solutions. It is against the Forum Rules (these can be found pinned to the top of the Maths Forum).

    xLog(4) is one of the simplifications when you take logs
