Question 858007: I am currently working on polynomials and exponents with multiply variables and long division. 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.

Look at the rules of exponents which you are learning; read them.
, combines rules of exponents and commutative property of multiplication and simple multiplication fact
, multiplying by 1 to simplify the complex fraction
You can put this solution on YOUR website! It's easier to show this on a piece of paper, so check out the following sheet of paper:
step 1 shows you the problem as i interpreted it.
step 2 shows you the solution.
step 3 shows you how i got 4 from 2 / 2^-1.
step 4 shows you how i got a^8 from a / a^-7.
step 5 shows you how i got 1 / b^7 from b^-3 / b^4.
the basic principles of exponent arithmetic that were used in this problem are:
