If `x^y=y^x and x^2= y`, where x and y are distinct positivereal numbers, then the value of `x+ 2y` is

If x + y = 1 where x and y are positive numbers, then the minimum value of 1/x + 1/y is

If x^(y)=y^(x) where x and y are distinct natural numbers , then find x+y .

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

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

If x sqrt(243) = y sqrt(867) , where x and y are coprime numbers, then the value of (x-y) is

If x^(3)+y^(3)+3xy=1 where x and y are to distinct real numbers then which of the following can be values of x and y.
