The summation shown in the image is:

$\sum_{i=1}^{10} 8$

This represents a constant sum, where the value "8" is added for each value of $i$ from 1 to 10. Since 8 is a constant, you can simply multiply 8 by the number of terms in the summation.

The number of terms is from $i = 1$ to $i = 10$, so there are 10 terms.

Thus, the sum is:

$\sum_{i=1}^{10} 8 = 8 \times 10 = 80$

Here are 5 related questions to expand on this:

1. What is a general formula for the sum of a constant over $n$ terms?
2. How does the summation change if the constant is not 8 but any other number?
3. Can you explain the difference between summing a constant and summing a variable term?
4. How does this concept apply when summing arithmetic series or geometric series?
5. What would happen if the lower limit of summation changed from 1 to another number, like 5?

Tip: When dealing with constant summations, the sum is always the product of the constant and the number of terms in the summation.
