Question

Multiply the expressions, and simplify.
(-10x^-5y^-2) · (-9x^-4y)

Answer 1

I do not think you wrote the problem correctly. Please use the equation key on the lower left to input

Answer 2

\[(−10x ^{-5} y ^{-2} )⋅(−9x ^{-4})\]

Answer 3

\[90x ^{-9}y ^{-2}= \frac{90}{x ^{9}y ^{2}}\]

Answer 4

is this the problem you wanted help with?

Answer 5

Also is there supposed to be a y after the x^-4?

Answer 6

yes sorry

Answer 7

there is a y after that

Answer 8

So then the answer is :\[\frac{90}{x ^{9}y}\]

Answer 9

90x^-1y^-3
90(xy)^-10
10x-^9y^-1
90x^-9y^-1

this are the ansers it gave me

Answer 10

Well, the answer I gave you is the same thing. They just wrote theirs with negative exponents. If you move x^9 to the numerator, it will be x^-9.
if you move y^1 to the numerator, it will be y^-1
