Simplify `(2+sqrt3)/(2-sqrt3)+(2-sqrt3)/(2+sqrt3)`

Simplify: (2 +sqrt 3)/(2-sqrt3) + (sqrt 3)/(sqrt 3)

(2-sqrt3)(sqrt3+2)

(2 - sqrt3)/sqrt3

(3 + sqrt2)(2-sqrt3)(3-sqrt2)(2+sqrt3)

Simplify (sqrt3+2)^2-(sqrt3-2)^2

If a=(2+ sqrt3)/(2- sqrt3) and b=(2- sqrt3)/(2+sqrt3) , then the value of a^2+b^2+ab is: यदि a=(2+ sqrt3)/(2- sqrt3) और b=(2- sqrt3)/(2+sqrt3) , तो a^2+b^2+ab का मान:

If a = (2 + sqrt3)/(2-sqrt3) and b = (2-sqrt3)/(2+sqrt3) then the value of (a^2+b^2+ab) is

Simplify (i) (4+ sqrt(5))/(4-sqrt(5))+(4-sqrt(5))/(4+sqrt(5)) (ii) (1)/(sqrt(3) + sqrt(2)) - (2)/(sqrt(5)-sqrt(3)) -(2)/(sqrt(2) - sqrt(5)) (iii) (2+sqrt(3))/(2-sqrt(3)) + (2-sqrt(3))/(2+sqrt(3)) + (sqrt(3)-1)/(sqrt(3)+1) (iv) (2+sqrt(6))/(sqrt(2)+sqrt(3))+(6sqrt(2))/(sqrt(6)+sqrt(3)) -(8sqrt(3))/(sqrt(6)+sqrt(2))
