simplify
`(sqrt6 + sqrt7)/(sqrt6 +sqrt7)`

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

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

(sqrt(6+2sqrt(5)))(sqrt(6-2sqrt(5)))

Simplify (sqrt5-sqrt2)(sqrt5+sqrt2)

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

Simplify {(\sqrt 5+\sqrt 3)\times (\sqrt 5 - \sqrt 3)}/(\sqrt 7- \sqrt 3)\times (\sqrt 7+ \sqrt 3)/(\sqrt 7+\sqrt 3)

Simplify : (sqrt(2))/(sqrt(6)-sqrt(2))- (sqrt(3))/(sqrt(6)+sqrt(2))

(4(sqrt(6) + sqrt(2)))/(sqrt(6) - sqrt(2)) - (2 + sqrt(3))/(2 - sqrt(3)) =

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

Simplify: sqrt(-4) + sqrt(-16)- sqrt(-25)
