x^2/3?

I realize that 3 is really 3^0, but changing the exponent from 0 to -0 doesn't do any me any good, because any exponent raised to 0 is equal to one. Would the 3 by itself in the denominator if put in the numerator become -3, or is there another principle you must follow? Is changing signs just for exponents or for whole numbers too? Just some clarification would be nice. Thanks for all your help.
