\[\sum_{i=0}^{3}i^3= \left( \frac{ n(n+1) }{ 2 } \right)^2\]
I mistyped i as n. i=0 should be n=0
A. 0^3 + 3^3 B. 0^3 + 1^3 + 2^3 C. 1^3 + 2^3 + 3^3 D. 0^3 + 1^3 + 2^3 + 3^3
Oh okay, so if you expand them you write out all the numbers before adding them together. You start with the i number so 0^3 all the way to 3^3. Whats in between?
