I know what the cases are but I am just wondering how we jumped from i^3 to i^2 did something divide out?
The i^3 is a typo. It should have been i^2 as it is in the second red line.
When we pulled out
(8/n^3) from SUM does "i" go down a power?

Dan You Are The Freak'in Man Thanks So Much!
I was just wanting to know where this extra "n" came from. See Purple. Thanks!
