Calculate:
f(x) = 3 - 3/3-2^(negative infinity)

how do you solve this algebraically

Solve what? Do you have to simplify this? Is it some kind of limit? Numerically if what you have is
$\displaystyle \frac{3 - 3}{3 - 2^{-\infty}}$
the value is 0. (But even that expression has problems because $\displaystyle 2^{-\infty}$ does not have an actual value.)

sinx
You will get 0 over some number that gets infinitely smaller in the denominator, which will simplify to 0.

It's not really a solution though. This seems, like topsquark suggested, to be some description of a limit problem.
