" 4.If "x=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2))" and "y=(1)/(x)" then show that "x^(2)+y^(2)+xy=99

If x=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) and y=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)), then x^(2)+xy+y^(2)=101(b)99(c)98(d)102

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

If x=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)) and y=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) find x^(2)+y^(2)

If x=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)) and y=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)), find 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 x^2+xy+y^2=

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(3)+sqrt(2))/(sqrt(3)-sqrt(2)) and y=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) find x^2+y^2

If x= (sqrt7+sqrt3)/(sqrt7-sqrt3) and xy = 1, show that (x^2+xy+y^2)/(x^2-xy+y^2) = 12/11
