Evaluate :
`( sqrt(m) + sqrt(n )) ( sqrt(m) + sqrt(n ))`

find the value of m,(sqrt(m+1)+sqrt(m-1))/(sqrt(m+1)-sqrt(m-1))=2m-(1)/(2)

(i) ((root(n)(a))^(sqrt(n)))^(sqrt(n))

Find underset( n rarr oo) ("lim") (sqrt( n^(2) + 1)+ sqrt( n ) )/( sqrt( n ^(2) + 1)- sqrt( n ) )

lim_ (n rarr oo) sum_ (n = 1) ^ (n) (sqrt (n)) / (sqrt (r) (3sqrt (r) + 4sqrt (n)) ^ (2))

If tantheta+sintheta=m and tantheta-sintheta=n , then the value of m^2-n^2 is equal to (a)4 mn (b) 2sqrt(mn) (c) 4sqrt(mn) (d) 2sqrt(m//n)

If m and n are natural numbers such that sqrt(7+sqrt(48))=sqrt(m)+sqrt(n) then m^(2)+n^(2)=

Evaluate : lim_(n to oo)[(sqrt(n))/((3+4sqrt(n))^(2))+(sqrt(n))/(sqrt(2)(3sqrt(2)+4sqrt(n))^(2))+(sqrt(n))/(sqrt(3)(3sqrt(3)+4sqrt(n))^(2))+.......+(1)/(49n)]
