`sqrt(10609)`

Simplify (sqrt(25.4016) - sqrt(1.0609))/(sqrt(25.4016) + sqrt(1.0609)) :

sqrt(8 + sqrt(57 + sqrt(38 + sqrt(108 + sqrt(169)))))=?

(sqrt(10)+sqrt(11)+sqrt(12))xx(sqrt(10)+sqrt(11)-sqrt(12))xx(sqrt(10)-sqrt(11)+sqrt(12))xx(sqrt(10)-sqrt(11)-sqrt(12))

sqrt(11)+sqrt(3),sqrt(20),sqrt(5)sqrt(15)+sqrt(22),sqrt(25),sqrt(10)3+sqrt(55),sqrt(15),sqrt(25)]|=

|{:(sqrt(14)+sqrt3,sqrt(20),sqrt5),(sqrt(15)+sqrt(28),sqrt(25),sqrt(10)),(3+sqrt(70),sqrt(15),sqrt(25)):}|=.......

(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)

Which is the greatest among (sqrt(19)-sqrt(17)),(sqrt(13)-sqrt(11)),(sqrt(7)-sqrt(5)) and (sqrt(5)-sqrt(3))?

The smallest of sqrt(8)+sqrt(5),sqrt(7)+sqrt(6),sqrt(10)+sqrt(3) and sqrt(11)+sqrt(2) is
