Simplify `(1)/(sqrt(1)+sqrt(2))+(1)/(sqrt(2)+sqrt(3))`

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

Simplify P=(1)/(2sqrt(1)+sqrt(2))+(1)/(3sqrt(2)+2sqrt(3))+...+(1)/(100sqrt(99)+99sqrt(100))

(1)/(sqrt(2)+sqrt(3))+(1)/(sqrt(3)+sqrt(4))

Simplify: (2)/(sqrt(5)+sqrt(3))+(1)/(sqrt(3)+sqrt(2))-(3)/(sqrt(5)+sqrt(2))

Simplify: (1)/(1+sqrt(2))+(1)/(sqrt(2)+sqrt(3))+(1)/(sqrt(3)+sqrt(5))

(iii) simplify (2)/(sqrt(5)+sqrt(3))+(1)/(sqrt(3)+sqrt(2))-(3)/(sqrt(5)+sqrt(2))

( Simplify: )/(sqrt(100)-sqrt(99))-(1)/(sqrt(99)-sqrt(98))+(1)/(sqrt(98)-sqrt(97))-(1)/(sqrt(97)-sqrt(96))+backslash+(1)/(sqrt(2)-sqrt(1))

Simplify: (1)/(sqrt(11-2sqrt(30)))*(3)/(sqrt(7-2sqrt(10)))(4)/(sqrt(8+4sqrt(3)))
