(sqrt(3-1))/(sqrt(3+1))=a-b sqrt(3)

If sqrt(3) = 1.73 find the value of : (2+sqrt(3))/(2-sqrt(3))+(2-sqrt(3))/(2+sqrt(3))+(sqrt(3)-1)/(sqrt(3)+1)-(sqrt(3)+1)/(sqrt(3)-1) .

Which of the following is equal to root(3)(-1)?(sqrt(3)+sqrt(-1))/(2) b.(-sqrt(3)+sqrt(-1))/(sqrt(-4)) c.(sqrt(3)-sqrt(-1))/(sqrt(-4))d.-sqrt(-1)

Let A={:[(sqrt(3),-1),(2+sqrt(3),a-sqrt(3))]:},B={:[(-sqrt(3),2),(2-sqrt(3),1+sqrt(3))]:} Find A+B.

((2+sqrt(3))/(2-sqrt(3))+(2-sqrt(3))/(2+sqrt(3))+(sqrt(3)-1)/(sqrt(3)+1)) simplifies to 16-sqrt(3)(b)4-sqrt(3)(c)2-sqrt(3) (d) 2+sqrt(3)

(sqrt(3)-1)/(sqrt(3)+1)xx(sqrt(3)-1)/(sqrt(3)-1)

(2+sqrt(3))/(2-sqrt(3))+(2-sqrt(3))/(2+sqrt(3))+(sqrt(3)+1)/(sqrt(3)-1)is

Let A={:[(sqrt(3),-1),(2+sqrt(3),1-sqrt(3))]:},B={:[(-sqrt(3),2),(2-sqrt(3),1+sqrt(3))]:} Find A+B.
