Simplify: `1/(sqrt(100)-sqrt(99))-1/(sqrt(99)-sqrt(98))+1/(sqrt(98)-sqrt(97))-1/(sqrt(97)-sqrt(96))+\ dot+1/(sqrt(2)-sqrt(1))` .

( 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 : sqrt(50) -sqrt(98)

(1)/(sqrt(9)-sqrt(8))-(1)/(sqrt(8)-sqrt(7))+(1)/(sqrt(7)-sqrt(6))-(1)/(sqrt(6)-sqrt(5))+(1)/(sqrt(5)-sqrt(4))=?

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

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

Simplify: 2sqrt(50)-3sqrt(98)+(1)/(3)sqrt(162)
