`(7+3sqrt(5))(7-3sqrt(5))` का वर्गमूल क्या है?

(7+3sqrt5)/(7-3sqrt5)=

(5sqrt(28))/(3sqrt(7))

The value of frac (7+3sqrt 5)(3 + sqrt 5)+frac(7 - 3sqrt 5)(3 - sqrt 5) lies between: frac (7 + 3 sqrt 5) (3 + sqrt 5) + frac (7 - 3 sqrt 5) (3 - sqrt 5) का मान के बीच है:

(2sqrt(7))/(sqrt(5)-sqrt(3))

The value of (7+3 sqrt5)/(3+sqrt5)-(7-3 sqrt5)/(3-sqrt5) lies between: (7+3 sqrt5)/(3+sqrt5)-(7-3 sqrt5)/(3-sqrt5) का मान किसके बीच में होगा

Simplify each of the following by rationalising the denominator: (7+3sqrt(5))/(7-3sqrt(5)) (ii) (2\ sqrt(3)-\ sqrt(5))/(2sqrt(2)+\ 3sqrt(3))

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?
