If `x=(sqrt(3)+1)/(sqrt(3)-1)` and `y=(sqrt(3)-1)/(sqrt(3)+1)` then find the value of `x^(2)+y^(2)`

If x=(sqrt(5)+1)/(sqrt(5)-1) and y=(sqrt(5)-1)/(sqrt(5)+1) find the value of x^(2)+y^(2)

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

if x=sqrt(3)+(1)/(sqrt(3)) and y=sqrt(3)-(1)/(sqrt(3)) then x^(2)-y^(2) is

If x=(sqrt3-1)/(sqrt3+1) and y=(sqrt3+1)/(sqrt3-1) then x^2-xy+y^2
