Answer 1

number above sigma is 5

Answer 2

please help meeee!!!

Answer 3

Well you can simplify k!/k to get


k!/k

(k*(k-1)!)/k

(k-1)!


So k!/k turns into (k-1)!

Answer 4

Now compute the sum

(1-1)!+(2-1)!+(3-1)!+(4-1)!+(5-1)!

(0)!+(1)!+(2)!+(3)!+(4)!

1+1+2+6+24

34


So \[\Large \sum_{k=1}^{5}\frac{k!}{k} = 34\]

Answer 5

Keep in mind that the first step of simplification is optional as you could have skipped it and still evaluated this.
