    can u explain how did u get "1/√(4+1/n) + 2" ??

    eduncle-logo-app

    take common factor n from numerator and denominator .

    Got it.... thank you

    I also want to know that why do we have to keep '1' in the numerator to solve these sums?

    eduncle-logo-app

    here we have no target to keep 1 in numerator . We have just cancelled common factor , and 1 automatically came . There may be anything in numerator .

    ok I understood now. Thanks a lot.
