But on this problem it is set up different and says use the rules of exponents: Division. The problem is 2^-1a^-7b^4 as the denominator and 2ab^-3 as the numerator. If someone could be advise me I would be grateful. I am horrible at math and always have been so please explain in detail. Thanks Shawna </SPAN>\n" );
