44*sqrt(sqrt(63)+sqrt(56))=

20-4sqrt(8)+7sqrt(18),sqrt(63)+sqrt(28)+sqrt(175)

(sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3))+(sqrt(5)-sqrt(3))/(sqrt(5)+sqrt(3))

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

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

4 sin 27^(0)= 1) sqrt(5+sqrt(5))+sqrt(3-sqrt(5)) 2) sqrt(5-sqrt(5))+sqrt(3+sqrt(5) 3) sqrt(5+sqrt(5))-sqrt(3-sqrt(5)) 4) sqrt(5+sqrt(5))+sqrt(3+sqrt(5)

(3sqrt(2))/(sqrt(3)+sqrt(6))-(4sqrt(3))/(sqrt(6)+sqrt(2))+(sqrt(6))/(sqrt(3)+sqrt(2))

If x=sqrt(56+sqrt(56+sqrt(56+....oo))) and y=sqrt(56-sqrt(56-sqrt(56....)) then which of the ) followinig true?

log_((4)/(3))(56+(sqrt(56+sqrt(56+sqrt(56+......oo))))/(sqrt(64sqrt(64sqrt(64.....oo)))))
