The reason this works is if you take a^-x/1 and multiply both top(numerator)and bottom(denominator) by a^x on the top you get a^-x times a^x and using the multiplication law of exponents this gives us  a^0 and any number raised to the zero power excluding zero itself equals 1. On the bottom 1 multiplied by a^x equals a^x. Another way to state this is when changing from a negative exponent to a positive you just invert the base and make the exponent positive.\r<BR>\n" );
