Please help me!

\[5x^{3}y + xy ^{4}+2xy \div xy\]

OpenStudy (anonymous):

except its suppose to be in fraction form...

OpenStudy (jlastino):

is 5x^3y + xy^4 + 2xy in the numerator?

OpenStudy (anonymous):

its the top and the xy is on the bottom

OpenStudy (jlastino):

Oh just reduce every exponent of x and y in the numerator by 1 then the denominator would be gone

OpenStudy (anonymous):

huh?

OpenStudy (anonymous):

so 5x^2+y^3+2?

OpenStudy (jlastino):

yup

OpenStudy (anonymous):

oh lol okay thank you

OpenStudy (anonymous):

^ that's actually incorrect, close though.

OpenStudy (anonymous):

you did it right, Riya.... good job

OpenStudy (anonymous):

-.-

OpenStudy (asnaseer):

RiyaMoon: what you have is totally correct. \[5x^3y+xy^4+2xy=xy(5x^2+y^3+2)\]therefore:\[\frac{5x^3y+xy^4+2xy}{xy}=\frac{\cancel{xy}(5x^2+y^3+2)}{\cancel{xy}}=5x^2+y^3+2\]

OpenStudy (anonymous):

I have no idea why you're multiplying the right side by xy(5x^2 + y^2 + 2), that's completely incorrect.

OpenStudy (jlastino):

@petewe 5x^3 is different from (5x)^3

OpenStudy (anonymous):

woops, read the equation wrong
