Simplify `(2+sqrt(3))(2-sqrt(3))`

Simplify: (sqrt(-2))/(sqrt(-8))

Simplify (5+sqrt(7))(5+sqrt(2))

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

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

Simplify: (2sqrt(3)+sqrt(5))(2sqrt(3)-sqrt(5))

Simplify (sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)) e

Simplify : sqrt(3+2sqrt(2))

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

Simplify: (i) (3sqrt(2)-2sqrt(2))/(3sqrt(2)+\ 2sqrt(3))+(sqrt(12))/(sqrt(3)-\ sqrt(2)) (ii) (sqrt(5)+\ sqrt(3))/(sqrt(5)-\ sqrt(3))+(sqrt(5)-\ sqrt(3))/(sqrt(5)+\ sqrt(3))

Rationales the denominator and simplify: (sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2))
