**Unformatted text preview: **. 5 x y n = x n y n The power of a quotient is the quotient of the powers . 6 x = 1 This is consistent with Law 2, with m = n . (We define to be 1 here. See Section 1.3, Part H.) 7 1 x n = x n This is consistent with Laws 2 and 6. 8 x y n = y x n x y 1 = 1 x y = y x y ( ) . Use Law 3 with m = 1 . WARNING 1 : These laws may or may not apply when the expressions involved are not real-valued; 2 ( ) 1/ 2 , for example, cannot be defined as a real value. Also, we require nonzero denominators in Laws 2, 5, 7, and 8....
