Fill `(2+sqrt3)+.......(-2sqrt3)=4-sqrt3`

(2 - sqrt3)/sqrt3

(2-sqrt3)(sqrt3+2)

(2+sqrt3)/2 + (5-sqrt3)/3

3(2 + sqrt3)(2 - sqrt3)

If tan15^@=2-sqrt3 , then the value of cot^2""75^@ (a) 7+sqrt3 (b) 7-2sqrt3 (c) 7-4sqrt3 (d) 7+4sqrt3

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:

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