I have a problem solving this equation for x - finding the maximum domains.(adsbygoogle = window.adsbygoogle || []).push({});

3(2^(2x+1)+5(2^(-x) )= 31

What I did first was to take the logarithim on both sides of the equation.... to solve for x. But that apparantly isn't a "logical" way to proceed. Any advice?
