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

sqrt(sqrt(63)+sqrt(56))=

(sqrt(56+sqrt(56+sqrt(56+...))))/2^(2)=?

If x=log_2(sqrt(56+sqrt(56+sqrt(56+sqrt(56+ . . . oo))))) then which of the following statement holds good?

If sqrt(y - sqrt(y - sqrt(y ....oo))) = sqrt(x + sqrt(x + sqrt(x ....oo))) then (dy)/(dx) is equal to

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

sqrt(y-sqrt(y-sqrt(y-......till oo)))=sqrt(x+sqrt(x+sqrt(x+......til_(oo)))) then (dy)/(dx)=

If a= (sqrt(5) + sqrt(2))/(sqrt(5) -sqrt(2)) and b = (sqrt(5)-sqrt(2))/(sqrt(5)+sqrt(2)) show that 3a^(2) + 4ab -3b^(2) = 4 +(56)/(3) sqrt(10)

Simplify: sqrt(216)-5 sqrt(6)+sqrt(294)-3/(sqrt(56))

Which is true for 56 and 84?
