Hi List,

I recently took a placement test with this problem in it.  It was very easy to solve but after getting home I suspected Maxima could not do it.  At least not directly.

(%i1) solve((3/7)^(4*x-5)*(7/3)^(2*x-7)=1,x);

(%o1) [3^(2*x+2) = 7^(2*x+2)]

Is there an easy way Maxima can do it?  The answer is -1.
