" f "(9^(y)*3^(2)*(3^(-y))^(-1)-27^(y))/(3^(3x)*2^(3))=(1)/(27)" then "x-y" is given by "

27x^(3)y^(3)-45x^(4)y^(2)

(x^(3))/(9y^(2))times(27y)/(x^(5)) =____.

If y= x^(1/3).x^(1/9).x^(1/27)...oo then y=?

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 to

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 to

If y=3^((1)/(3))+3, then y^(3)-9y^(2)+27y=
