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

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

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

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

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

Simplify: (4+\ sqrt(5))/(4-sqrt(5))+(4-\ sqrt(5))/(4+\ sqrt(5))

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

Rationlise the denominator and simplify: (2)/(sqrt5+ sqrt3)

Rationales the denominator and simplify: (i) (sqrt(3)-\ sqrt(2))/(sqrt(3)\ +\ sqrt(2)) (ii) (5+2\ sqrt(3))/(7+4\ sqrt(3))

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

Rationlise the denominator and simplify: ( 12sqrt2)/( sqrt3+ sqrt6)
