lim (n to inf) [ ln (1+3n+4n^2) - ln(5+6n+2n^2) ]

lim (n to inf) [ ln (1+3n+4n^2) - ln(5+6n+2n^2) ]


My Friend and I have trouble on this question


what I do is this:


lim (n to inf) [(1+3n+4n^2)/(5+6n+2n^2)] and then L'hopital's. the answer I got is 1


My friend write is like this:


ln lim(n to inf) [(1+3n+4n^2)/(5+6n+2n^2)]. she factor n^2. and the final answer is ln(2)


We did similar question at class : lim (n to inf) sin(1/sqrtn) --> sin lim (n to inf) (1/sqrtn)


We want to know what could be possibly wrong?
