(2+sqrt(3))/(sqrt(3))

If a=(2 + sqrt(3))/(2-sqrt(3)) and b = (2-sqrt(3))/(2+ sqrt(3)) , then the value of a^(2)+b^(2)+ab is :

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

Domain of f(x)=sin^(-1)[2-4x^2], where [.] denotes the greatest integer function, is: (a)[-(sqrt(3))/2,(sqrt(3))/2]-{0} (b) [-(sqrt(3))/2,(sqrt(3))/2] (c)[-(sqrt(3))/2,(sqrt(3))/2)-{0} (d) (-(sqrt(3))/2,(sqrt(3))/2)-0

Domain of f(x)=sin^(-1)[2-4x^2], where [.] denotes the greatest integer function, is: (a)[-(sqrt(3))/2,(sqrt(3))/2]-{0} (b) [-(sqrt(3))/2,(sqrt(3))/2] (c)[-(sqrt(3))/2,(sqrt(3))/2)-{0} (d) (-(sqrt(3))/2,(sqrt(3))/2)-0

(2+sqrt(3))/(2-sqrt(3))+(2-sqrt(3))/(2+sqrt(3))=

(5+sqrt(3))/(2-sqrt(3))+(2-sqrt(3))/(2+sqrt(3))

((2+sqrt(3))/(sqrt(2)+sqrt(2+sqrt(3)))+(2-sqrt(3))/(sqrt(2)+sqrt(2-sqrt(3))))^(2)=

The value of (2+sqrt(3))(2-sqrt(3)) is:

(3sqrt(2)-sqrt(3))(4sqrt(3)-sqrt(2))
