`(5+sqrt6)/(5-sqrt6)times(5+sqrt6)/(5+sqrt6)=?`

(5+sqrt3)/(3+sqrt6)

(6 + sqrt6)(6 - sqrt6)

Evaluate : sqrt(5)times sqrt(6)

6/(sqrt5 + sqrt3)

6/(sqrt5 - sqrt3)

6/(sqrt5 + sqrt3)

(6+sqrt(5))/(6-sqrt(5))

Simplify each of the following by rationalising the denominator: (1)/(5+sqrt(2))( ii) (5+sqrt(6))/(5-sqrt(6))

(2)/(sqrt(5)+sqrt(3))-(3)/(sqrt(6)+sqrt(3))+(1)/(sqrt(6)+sqrt(5))=?
