The differential equation dydx=72/(y^1/4+64x^2y^1/4) has an implicit general solution of the form F(x,y)=K, where K is an arbitrary constant. In fact, because the differential equation is separable, we can define the solution curve implicitly by a function in the form F(x,y)=G(x)+H(y)=K Find such a solution and then give the related functions requested. F(x,y)=G(x)+H(y)=
