Question

a

Answer 1

This is easy.

Answer 2

you just cancel the amounts of x and y and z

Answer 3

the bottom part has more x's so you're left with 2 x's on the bottom, the y completely cancels, and you get 4 z's on top.

Answer 4

then you're left with -45z^4/9x^2

Answer 5

then -45/9 = -5

Answer 6

so the final answer is -5z^4/x^2

Answer 7

The way i think about it is expanding it so the exponents go away and you just get a bunch of x's y's and z's with the same amount as the exponent shows.

Answer 8

Thanks, you were close. it's actually -5z^4 / x^-2 Your x was subtracted bottom to top
