Please help, don't know where to begin

b(i) use the Quotient Rule to differentiate the function

h(x) =1+Inx

x (x>0).

ii) using your answer to part (b) (i), find the general solution of the differential equation

dy/dx=(-inx/x^2)(y^1/2) (x>0,y>0)

Give the solution in implicit form.

(iii) Find the particular solution of the differential equation in part (b) (ii) for which y=1 when x=1, and then give this particular solution in explicit form.

Thank you in advance
