If `x=3-sqrt(7), y=sqrt(8)-sqrt(6), z=sqrt(7)-sqrt(5)` then

If x=sqrt(7)-sqrt(5),y=sqrt(5)-sqrt(3),z=sqrt(3)-sqrt(7) then find the value of x^(3)+y^(3)+z^(3)-2xyz

If x=sqrt(7)-sqrt(5) and y=sqrt(13)-sqrt(11) then

given x=(sqrt(7)+sqrt(3))/(sqrt(7)-sqrt(3)),y=(sqrt(7)-sqrt(3))/(sqrt(7)+sqrt(3)) find the value of x^(4)+y^(4)+(x+y)^(4)

(sqrt(7)-sqrt(5))^3 - (sqrt(7)+sqrt(5))^3

If x=(sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3)) and y=(sqrt(5)-sqrt(3))/(sqrt(5)+sqrt(2)), then x+y+xy=9(b)5(c)17(d)7, then

(5sqrt(7)+2sqrt(7))(6sqrt(7)+3sqrt(7))=?
