`(sqrt4!)/(sqrt5!)`

((4 +sqrt5)/(4-sqrt5)) +((4-sqrt5)/(4+sqrt5)) =?

Find the sum of the following series: 3/(sqrt5)+4/sqrt(5)+… 25 terms

lim_(xrarr 1) (sqrt(4+x)-sqrt(5))/(x-1)

किसी घनात्मक पूर्णांक n के लिए यदि, (1)/(sqrt(4)+sqrt(5))+(1)/(sqrt(5)+sqrt(6)) +(1)/(sqrt(6)+sqrt(7)) +..... + (1)/(sqrt(n)+sqrt(n+1))=5 है तो n का मान क्या होगा?

Prove that: 1/(1+sqrt(2))+1/(sqrt(2)+sqrt(3))+1/(sqrt(3)+\ sqrt(4))+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))=2

If (4+3sqrt5)/(4-3sqrt5)=a+bsqrt5 ,a, b are rational numbers, them (a, b)=

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

(sqrt(5)-sqrt(3))/(sqrt(5)+sqrt(3)) Is equal to :

Evalutate : (4-sqrt(5))/(4+sqrt(5))+ (4+sqrt(5))/(4-sqrt(5))

Solve : (4-sqrt(5))/(4+sqrt(5))+ (2)/(5+sqrt(3))+(4+sqrt(5))/(4-sqrt(5))
