You're right about x^0
of course but your example of x^(1 + -1) doesn't look right. x^(1 + -1)
reduces to x^0 not x * 1/x.
x^0 = 1 x*1/x = 1, so they are the same. To take concrete examples: x^2 *
x^3 = x^(2+3) = x^5, say 2^2 * 2^3 = 8 * 16 = 128, 2^5 = 128
I certainly agree that they give the same result. What I said was that one
does not direcly reduce to the other. The expression could be written
x^0 = x * 1/x
I think this is all a matter of semantics.

A fair fight is the result of poor planning.
