    \[{dy \over dx} = 3x^{\large3}y\]Actually, that's the question for everyone's clarification.

    \[\frac{ dy }{ y} = { x ^{3}dx}\]

    \[\frac{dy}{dx} =3x^{3} y => \frac{dy}{y} =3x^3dx => \int\limits\frac{dy}{y} =\int\limits3x^{3}dx => \ln(y)=\frac{3x^{4}}{4} +C\] i think you have to find the analytical solution next

    then if i take ln of both sides i should get the whole right side in exponent form??
