Question

Which statement correctly defines a negative integer exponent for a nonzero base aa and positive integer nn?

Accepted Answer

a−n=1an\displaystyle $$a^{-n}$$=\frac{1}{$$a^{n}$$}

Answer

a−$$na^{-n}$$  gives a negative result when nn is odd, and positive when nn  is even.

Answer

a−n=$$ana^{-n} = a^n $$

Answer

a−n=(−$$a)na^{-n} = (-a)^n $$
