a. If c is a constant then the sum of such constants is the same as multiplication of constants. Therefore $\Sigma_{k=1}^{n}c=nc$

b. $\Sigma_{k=1}^{n}k=1+2+3+\dots+\infty=\infty$

c. $\Sigma_{k=1}^{n}k^2=1+4+9+\dots+\infty=\infty$

d. $\Sigma_{k=1}^{n}k^3=1+8+27+\dots+\infty=\infty$

Hope this helps.
