If `y=f(x)` is solution of differentiable equation `(dy)/(dx)=y/x((1-3x^(2)y^(3)))/((2x^(2)y^(3)+1))`, then (`f(x).x)^(3)` is equal toA. `x+cy`B. `2x+cy`C. `x^(2)+cy`D. `x^(3)+cy^(2)`

Answer» Correct Answer - A
`x(2x^(2)y^(3)+1)dy=y(1-3x^(2)y^(3))dx`
`impliesx^(2)(2xdy+3ydx)=(ydx-xdy)/(y^(2))`
`impliesd(x^(3)y^(2))= x/y +c`
`impliesx^(3)y^(3)=x+cy`
