Question in post-->

OpenStudy (anonymous):

\[\int\limits_{R}^{}\int\limits_{}^{}6xy ^{2}dA= \int\limits_{1}^{2}\int\limits_{2}^{4}6xy ^{2} dxdy\] how do I solve for the answer?

OpenStudy (anonymous):

@AloneS Help?

OpenStudy (anonymous):

The answer is 84 .-.

OpenStudy (anonymous):

@Anaise Do you know how to show the work for this?

OpenStudy (anaise):

I don't help in math, although I didn't even read it.

OpenStudy (anonymous):

lol welp

OpenStudy (anaise):

No way.

OpenStudy (anonymous):

do this \[\int\limits_{2}^{4}6xy ^{2} dx\] first

OpenStudy (anonymous):

i know the answer but the work to it slips my mind and woah indeed

OpenStudy (anonymous):

lemme work that out

OpenStudy (anonymous):

the anti - derivative wrt \(x\) is \[3x^2y^2\] plug in 4 and 2, then subtract

OpenStudy (anonymous):

ok i come out with \[\int\limits_{1}^{2}36y^2dy\]

OpenStudy (anonymous):

so that means next step gives \[12y^3|^2_1\] right? @satellite73

OpenStudy (anonymous):

Which =84.
