sqrt(2)+sqrt(7-2sqrt(10))

What is rationalizing factor of sqrt(2)+sqrt(7)+sqrt(10)

Simplify (sqrt(7)+sqrt(2))(sqrt(7)-sqrt(2))

(1)/(sqrt(2)+sqrt(5)-sqrt(7))

Value of 1/sqrt(11-2sqrt30)-3/sqrt(7-2sqrt10)-4/(sqrt(8+4sqrt3)) is

sqrt(7+2sqrt(6))+sqrt(7-2sqrt(6)) =______.

(sqrt(7)+2sqrt(3))(sqrt(7)-2sqrt(3))

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

(12)/(3+sqrt(5)+2sqrt(2)) is equal to 1-sqrt(5)+sqrt(2)+sqrt(10) (b) 1+sqrt(5)+sqrt(2)-sqrt(10) (c) 1+sqrt(5)-sqrt(2)+sqrt(10) (d) 1-sqrt(5)-sqrt(2)+sqrt(10)

sqrt(10+2sqrt(6)+2sqrt(10)+2sqrt(15)) is equal to (sqrt(2)+sqrt(3)+sqrt(5))(sqrt(2)+sqrt(3)-sqrt(5))(c)(sqrt(2)+sqrt(5)-sqrt(3))(d) None of these
