Consider the function $f(x)=x^{2},0\leq x\leq 8$. Which of the following represents a right-hand Riemann sum for the function?

$\cfrac{8}{n}\sum_{i=0}^{n-1}\left ( \cfrac{8i}{n} \right )^{2}$

$\cfrac{8}{n}\sum_{i=1}^{n}\left ( \cfrac{8i}{n} \right )^{2}$

$\cfrac{8}{n}\sum_{i=1}^{n}\left ( 8i \right )^{n}$

$\cfrac{8}{n}\sum_{i=1}^{n}\left ( i \right )^{n}$
