Root test for convergence

Can someone assist me in solving this?


"Use te nth-root test to find the conditions on the constant α in order that the series

$\displaystyle \sum _{n=1}^{\infty \:}\left(\frac{αn}{αn+1}\right)^{n^2}i^n$


is absolutely convergent[/QUOTE]

I made a mistake in the formula and could not edit as it was longer than 60min.
