$3+3+3+3+3+3+3+3$

Step-by-Step Solution

Answer

The sigma notation is $\sum _{k=1}^{8}3 \mathrm{and} m=1, n=8, a_k=3$

Step 1. Given Information

The given sum is $3+3+3+3+3+3+3+3$

Step 2. Explanation

The sum in sigma notation is written as,

$$\begin{gathered} 3+3+3+3+3+3+3+3=3\left(1+1+1+1+1+1+1+1\right) \\ =\sum _{k=1}^{8}3 \\ where, \\ m=1, n=8, a_k=3 \end{gathered}$$
