(-9)^7

Answer 1

when you divide these, you subtract the exponents.

\(\Large\color{blue}{ \bf (-9)^{10} × (-9)^{-3}=(-9)^{10--3} =(-9)^{10+3} =? }\)

Answer 2

when finding powers, it's going to end up positive if it's squared to an even power or negative if squared to an odd power. So since 7 is odd, just multiply 7 x 9 then put a negative on it.

Answer 3

my bad, you add, it's multiplication.

Answer 4

\[(-9)^{10+(-3)} \]
