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 Lisi --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
