If `x+y=a` and `x^2+y^2=b`, then the value of `(x^3+y^3)`, is

If x,y are real and (x-1)^(2)+(y-4)^(2)=0 then the value of x^(3)+y^(3) is

If x-3y=2 and x+y=6 , then the values of x and y will be

If (x+y)/(x-y)=5/3 and x/(y+2)=2 , then the value of (x,y) is

If x^(2)+y^(2)=49 and x-y=3, then find the value of x^(3)-y^(3)

If x =a , y = b is the solution of the pair of equation x - y = 2 and x + y = 4 then the value of 3a + 4b is …….. .

If x=2 and y=3 , find the value of x^x + y^y =
