\(\displaystyle \sum_{n=3}^{\infty} \frac{2n+8}{[n ln(n)]^2 +4}\)

Can anyone give me some input as to what I could compare this to. At first glance, maybe I could do a limit comparison test with
bn= \(\displaystyle \frac{2n}{[n ln(n)]^2}\) , which would simplify to \(\displaystyle \frac{2}{n [ln(n)]^2}\)

Since n is the dominant term, would I compare it with the harmonic series of \(\displaystyle \frac{1}{n}\) ??

Any feedback appreciated. Thanks.
 
Are you SURE your new bn is strictly greater than your original? Prove it.
