Enter your answer as the example: 1+2+3+4+5=15

Answer 1

\[\sum_{k=1}^{5} k ^{3}\]

Answer 2

it is the sum from k = 1 to k = 5 [from the bottom and top of sigma respectively]

which is:

\[1^3 + 2^3 + 3^3 + 4^3 + 5^3\]

Answer 3

oh i see! so you add all of them up till 5 and that whole equation is the answer?

Answer 4

yes :)

Answer 5

the exmaple in the question that added to 15 is just \[\sum_{1}^{5} k\]

Answer 6

haha alright thanks :)
