If `y= root(3)3 + 1/root(3)3,` then the value of `3y^3 - 9y` is:

If x= ( root(3) (m+1) + root(3) (m-1))/( root(3) (m+1) - root(3) (m-1)) then the value of x^3 - 3mx^2 +3x -m is

If x - y = 1 , then the value of x^3 - y^3 - 3xy will be :

If x-y=1,then the value of x^3-y^3-3xy will be :

If x+y=1 then the value of (x^(3)+y^(3)+3xy) is

If x = root(3)(sqrt9 + 1) - root(3)(sqrt9-1) , the value of x^(3) + 6x =

If ( y - (1)/( y ) )^(3) = 27 , then find the value of y^(3) - (1)/( y^(3))

If xy(x + y) = 1 then,the value of 1/(x^3 y^3) -x^3 - y^3 is
