Wyatt claims that is equivalent to Which statement about his claim is true in every aspect? A true, because (Wyatt used properties of exponents to simplify the expression.)
B true, because the gives 9 and will cause the signs to alternate (Wyatt knows that negative exponents alternate the signs.)
C false, because a base of and 9 cannot be combined into a single base for a power (It does not matter that Wyatt dropped the negative.)
D false, because when combined in this manner, the alternating signs of the series are lost (Wyatt ignored the negative in the first factor.)
