Hello!
it looks like a very simple one:
$\displaystyle 3^{(x/2)}+1=2^x$
as you can see x=2.
the question is: find x. meaning, find it, as if you don't know that x=2. also don't prove x=2 is right, and don't prove it's the only one.
I need to prove it analytically, and my brain is going mad because of that,
can someone help?
Thanks a lot.
