(-9)^7 x (-9)^2 x (-9)^8

Question

Math help needed immediately, in other words, cluessless.

Answer 1

each of the terms is a power with base = -9

 

the exponents from left to right are 7, 2, and 8

 

when you multiply powers with the same base, you can combine them into a single power by adding the exponents.

 

in general it looks like this:  m^A x m^B = m^A+B

 

(-9)^7 x (-9)^2 x (-9)^8 = (-9)⁷⁺²⁺⁸ = (-9)¹⁷
