This is just a trivia question posted on a site I go to. I've been racking my brain for hours now and I can't come up with an answer because I don't think enough information is given. If it is solvable, any tips on how to do it... or the outright answer would be helpful :P

If you mean log(4) base (x) = 2:
This means x^2 = 4
x = 2
----------
If
log(a) base (c) = b
then
c^b = a

The given equation yields x² = 4, with x positive,
since the base of a logarithm must be positive.
Thus, x = 2.

x = 2? I think. Because x is the base number, 2 is the power, and 4 is what is equals, so x^2 = 4, therefore x must be 2, right?

Hi,
If you mean log{base x} 4 =2. Then coverting that to exponential:
x^2 = 4
x^2 = 2^2
x = 2

The problem is easier than you think.
logx 4 = 2
simply means that
x^2 = 4
and the answer is x = 2.
