Question

Evaluate this sigma notation? / Summation notation?

Answer 1

is it clear what this means?

Answer 2

\[\sum_{k=1}^5\frac{k!}{k}=\frac{1!}{1}+\frac{2!}{2}+\frac{3!}{3}+\frac{4!}{4}+\frac{5!}{5}\]

Answer 3

might have been more clever to note that \(\frac{k!}{k}=(k-1)!\) at the beginning, but no matter, you still have to add

Answer 4

=0!+1!+2!+3!+4!=1+1+2+6+24=34
