This would be alot easier if I could do the html markup for it, but here goes:

lim as n ==> oo

n is above the epsilon, k=1 below of:

(1-(k/n))^3 (2/n)

Evaluate

For a summation involving i^3, the summation formula is (n^2(n+1)^2)/4 but thats as far as I can get as far as where to start. Help? and thanks!
