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. 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 want to know what could be possibly wrong?
