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

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

Simplify : (\sqrt 5 - \sqrt 3)/(\sqrt 3 + \sqrt 5) \times (\sqrt 5 - \sqrt 3)/(\sqrt 3 -\sqrt 5)

(3 - sqrt(3))(3+sqrt(3)) =

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

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

Simplify : (7)/(sqrt(17) - 2sqrt3)-( 3)/(sqrt(17) +2sqrt3)

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

Simplify: (i) (7+3\ sqrt(5))/(3+\ sqrt(5))-(7-3\ sqrt(5))/(3-\ sqrt(5)) (ii) 1/(2+sqrt(3)\ )+2/(sqrt(5)-\ sqrt(3))+1/(2-\ sqrt(5))

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

Find: (sqrt7 +sqrt3)(3-sqrt3)
