Calculus,help?

can any one tell me the answer(detail) for this question please?1.use quotient rule to differentiate the function f(x)=(1+lnx)/x (x>0), 2.using your answer to the above question,find the general solution of the differential equation dy/dx=(lnx/x^2)*y^(1/2) (x>0,y>0),giving the solution in implicit form.3.find the particular solution of the differential equation in part 2 for which y=1 when x=1 and then give this particular solution in explicit form.thank you.
