    1. An exponent of zero makes the power equal to 1. 2. A negative exponent in the numerator is a positive exponent in the denominator, and vice-versa.

    On the top line in the figure above, notice every time you have an exponent of zero, the expression is simply 1.

    On the bottom line above, notice the x had an exponent of -2 in the numerator, so it becomes a positive 2 exponent in the denominator. The w had a negative exponent in the numerator, so it becomes a positive exponent in the numerator.

    x^(-2) in the numerator is x^2 in the denominator 2^(-1) in the denominator is 2^1 in the numerator, but 2^1 = 2 |dw:1438831799460:dw|
