    2^(1 + 2x )= 3 take the log_2 of both sides: 1+2x = log_2 3 subtract 1 from both sides: 2x = (log_2 3) - 1 divide by 2 x = [(log_2 3) - 1]/2

    you didn't specify the way you wanted the solution... and -1/2 is not what I came up with. it's x = [(log_2 3) - 1]/2 did you want a calculator answer?

    http://www.wolframalpha.com/input/?i=%5B%28log_2+3%29+-+1%5D%2F2 if that doesn't work use a calculator from the applications section. Those have been there since time immemorial.

    0.292... is the "right" answer. If you want the most accurate answer you take the thing with the log.
