Hello! at first i thought this one is very easy: 3^(x/2)+1=2^x the question is: find x, analiticly. meaning, solve it as if you didn't know that x=2, also don't prove x=2 is the only answer, or that it is an answer. don't guess the answer... find it analiticly. and when you do.... please do publish, my brain hurts already... Thanks!
