`(sqrt(8)+sqrt(3))/(sqrt(8)-sqrt(3))+ (sqrt(8)-sqrt(3))/(sqrt(8)+sqrt(3))`

(sqrt(2)-sqrt(8))/(sqrt(2)+sqrt(8))

(sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3))+(sqrt(5)-sqrt(3))/(sqrt(5)+sqrt(3))+(sqrt(8)+sqrt(7))/(sqrt(8)-sqrt(7))-(sqrt(8)-sqrt(7))/(sqrt(8)+sqrt(7))=a+b sqrt(14) Find the value of (a-b) (a) 8, (b) 16 (c) 4, (d) 0

(sqrt(8)-sqrt(3))(-4+sqrt(3))

(2sqrt(6))/(sqrt(2)+sqrt(3))+(6sqrt(2))/(sqrt(6)+sqrt(3))-(8sqrt(3))/(sqrt(6)+sqrt(2))

3+ 1/(sqrt(4)+sqrt(5))+1/(sqrt(5)+sqrt(6))+1/(sqrt(6)+sqrt(7))+1/(sqrt(7)+sqrt(8))+1/(sqrt(8)+sqrt(9))= a)4 b)3 c)2 d) 3-sqrt(8)

Let T = (1)/(3-sqrt(8))-(1)/(sqrt(8)-sqrt(7)) +(1)/(sqrt(7)-sqrt(6))-(1)/(sqrt(6)-sqrt(5))+(1)/(sqrt(5)+2) then-

(1/(3-sqrt(8))-1/(sqrt(8)-sqrt(7)))

( Show that: )/(3-sqrt(8))-(1)/(sqrt(8)-sqrt(7))+(1)/(sqrt(7)-sqrt(6))-(1)/(sqrt(6)-sqrt(5))+(1)/(sqrt(5)-2)=5
