`sqrt(5^2sqrt(5^2sqrt(5^2sqrt(5^2`

What is (5+sqrt(10))/(5sqrt(5)-2sqrt(20)-sqrt(32)+sqrt(50)) equal to? (a) 5 (b) 5sqrt(2)(c)5(d)sqrt(5)

sqrt(12sqrt(5)+2sqrt(55))=

(sqrt(5)-sqrt(2))(sqrt(5)+sqrt(2))

sqrt(5sqrt(2)-2sqrt(12))=

(sqrt(sqrt(5)+2)+sqrt(sqrt(5)-2))/(sqrt(sqrt(5)+1))-sqrt(3-2sqrt(2))

N=(sqrt(sqrt(5)+2)+sqrt(sqrt(5)-2))/(sqrt(5)+2)-sqrt(3-2sqrt(2)) then the value of N

N=(sqrt(sqrt(5)+2)+sqrt(sqrt(5)-2))/(sqrt(5)+2)-sqrt(3-2sqrt(2)) then the value of N

[ If N=(sqrt(sqrt(5)+2)+sqrt(sqrt(5)-2))/(sqrt(sqrt(5)+1))-sqrt(3-2sqrt(2)) then N equals [ (A) 1, (B) 2sqrt(2)-1 (C) (sqrt(5))/(2), (D) (2)/(sqrt(sqrt(5)+1))]]

(sqrt(5)-sqrt(2))(sqrt(5)+sqrt(2))^(2)
