(1)/(sqrt(7)-2)

Show that : (1)/(3-2sqrt(2))- (1)/(2sqrt(2)-sqrt(7)) + (1)/(sqrt(7)-sqrt(6))-(1)/(sqrt(6)-sqrt(5))+(1)/(sqrt(5)-2)=5 .

(1)/(sqrt(7)-sqrt(2))-(1)/(sqrt(7)+sqrt(2))=

Rationalize the denominators or the following ( 1)/( sqrt7-2)

The value of (1)/(2+sqrt(7))+(1)/(sqrt(7)+sqrt(10))+......+(1)/(sqrt(28)+sqrt(31))

Rationailise the denominatios (1)/(sqrt(7)+sqrt(2))-(sqrt(7)+sqrt(2))/(sqrt(7)-sqrt(2))

sqrt(2)+sqrt(3)+sqrt(7)-(1)/(sqrt(2)+sqrt(3)+sqrt(7))=?

Prove that the following are irrationals (1) (1)/sqrt(2) (2) 7sqrt(5) (3)6+sqrt(2)

int(1)/(sqrt(x^(2)+7))dx
