Homework Help: Determining convergence of a series

  1. Apr 20, 2008 #1
    1. The problem statement, all variables and given/known data
    Determine if the following is convergent or divergent
    [tex]\Sigma\frac{n+5}{\sqrt[3]{n^7+n^2}}[/tex] n from 1 to infinity


    2. Relevant equations
    Test for divergence came up with limit = 0 so I know it converges.


    3. The attempt at a solution
    Ratio test came up inconclusive. Should I try rationalizing the denominator?

    use a comparison test, and then u can see if diverges or converges
