ltrout · Answer

Combine Like Terms
$$-28x ^{5}y ^{3} + 13x^{5}y \div -4x^{4}y^{2}$$

Simplify them:
$$28xy^{2} - 13x \div 4y$$

elisaneedshelp · Answer

well 28/4 is 7 but then 13/4 should turn into a fraction and remain that way...? My wrong answer was 7xy+ 13x/4y

ltrout · Answer

Let me check it again, I believe $$28xy^{2} - 13x \div 4y$$ is the simplest it will go. I'll check again

ltrout · Answer

Yes that is the simplest it will go. :)

that's the answer?

elisaneedshelp · Answer

I just checked now and my electronic workbook said that I had the sign wrong :/ so i guess I was mostly right :)

ltrout · Answer

So it was able to be simplified even further? O.o

yeah but don't worry I'm in intensive math on my senior year so I get your confusion too. :D
