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

Simplify: (i) (2 sqrt(2) + 3 sqrt(3)) (2 sqrt(2) - 3 sqrt(3)) (ii) (2 sqrt(8) - 3 sqrt(2))^(2) (iii) (sqrt(7) + sqrt(6))^(2) (iv) (6 - sqrt(2))(2 + sqrt(3))

Simplify (sqrt5 - sqrt3)(sqrt5 + sqrt 3)

Simplify : 2 /( sqrt(6) times sqrt(3) )

Simplify: (sqrt3 +1 ) (sqrt 3 - 1) (2 + sqrt 3) ( 2 - sqrt3)

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

Simplify (3 + sqrt(3))(2+sqrt(2))^(2) .

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

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