Answer:
Explanation:
we would like to compute the following limit:
if we compute the limit from numerator to denominator directly,we'd end up with
which is an indeterminate form so we must do it in a different way. well to compute this limit,we can consider factoring method . notice that we can factor the numerator and that yields
remember that ,
thus we acquire:
reduce fraction:
as n approaches to ∞ ,3/n approaches to 0 which yields:
simplify square root:
reduce fraction:
hence,
and we're done!
