Logic test returning unexpected answer
2^(x) == 1/(2^x) is returning 0. Any idea why?

Not surprising, because == doesn't do any and all simplifications for you.
Try (x1)*(x+1) == x^21 also returns 0. But x^21 == x^21 returns 1.

Yes, don't skimp on the '*'!

Using the method, simplify(fg)==0, works pretty well  where f ang g are the two items being compared.
For example: simplify(2^(x)  1/(2^x))==0
