I know when you move an exponent from the denominator to numerator it becomes negative, and vice versa, but what about a whole numbers?
3/x^2 can also be written as 3x^-2
but what about
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.
