# How can I prove that something converges using the limit comparison test when I can't seem to find something to which it compares?

I’m working with (ln(n))^3 / n^3. No matter what I attempt to compare this function to, it always results in a failure of the test – either an / bn converges while the summation of bn diverges or vice versa. Is there something I’m missing here?
