Given:
The expression is:
[tex]\sum\limits_{n=0}^{27}8n[/tex]
To find:
The expression that is equivalent to the given expression.
Solution:
According to the property of summation:
[tex]\sum\limits_{n=0}^{k}Cn=C\sum\limits_{n=0}^{k}n[/tex]
Where, C is a constant.
We have,
[tex]\sum\limits_{n=0}^{27}8n[/tex]
Using the above mentioned property of summation, we get
[tex]\sum\limits_{n=0}^{27}8n=8\sum\limits_{n=0}^{27}n[/tex]
The expression [tex]8\sum\limits_{n=0}^{27}n[/tex] is equivalent to the given expression.
Therefore, the correct option is C.
