Test the series for convergence or divergence. The sum figure from K=1 to infinity 2 / ((k^2)*(1+k^2))^(1/3)

so what we conclude?
Convergent. Thanks! Why did you use 4/3?
from what i remember if it`s goes to zero faster then 1/x it is convergencing and it does (don`t have the proof with me)
ah, it's quite simple. since it's for each then it's obvious that and you'll get the inequality.
