Question 183838: Ok! So, in the past few days, my algebra teacher left on family matters for a few days... Before she left, she gave our class a paper that she didn't exactly have time to sit down and explain how to do. The sub we had wasn't exactly great at this stuff either, so if you could explain what I'm supposed to do in these problems, that would be excellent!
(-2x^4y^2 * x^3y^-2)^4
-----------------------
xy^4
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
[(-2x^4y^2 * x^3y^-2)^4] / [xy^4]
= [-2x^7]^4 / [xy^4]
= [16x^28] / [xy^4]
= [16x^27] / [y^4]
===============================
Cheers,
