Summation
Evaluate these summations.
a) N(E)k=1 (kk^3)
b) N1(E)k=1 (k^2/N^2)
Note that (E) is the summation symbol.
Not sure how to do these. Help would be appreciated

Best ResponseYou've already chosen the best response.0sorry it's all squashed together, didn't notice! there are two questions: a) N (E) k=1 (kk^3) b) N1 (E) k=1 (k^2/N^2) where N = natural numbers and (E) is the summation symbol The N and N1 for the questions are on top of the summation symbol and the k =1 are below the symbol. The (kk^3) and (k^2/N^2) are on the right sides of the summation symbol.
