Homework Help: Integral Test: What should I compare this series with to prove it's convergence?

    1. The problem statement, all variables and given/known data
    Here is the problem:

    3. The attempt at a solution
    I know it is convergent because it is very similar to 1/n^1.5 which is convergent as well. However what would I compare this with using the Integral Test to prove that it is convergent?

    Compare it with [itex]\frac{\sqrt{2n+2n}}{n^2}[/itex]. Then it's even more similar to 1/n^(1.5).
