Question: How to get maple to perform first order ode

I was asked to derive the corresponding first order equation by differentiating this equation but I have no idea how to. Can someone help me thanks.

 

The equation I have to work with is x^(1/3)*(y(x)^2+5y(x)) + 3*(x^2+y(x)^2)*sin* (xy(x)) = k
