    This lesson shows a different way of thinking about the quotient rule for exponents -- this time, we look at subtracting the bottom exponent minus the top exponent and putting the answer in the denominator. A couple of different methods of simplifying expressions are shown on many example problems. The examples done start to get more challenging as this lesson goes on.
