Given:

The expression is:

$\sum\limits_(n=0)^(27)8n$

To find:

The expression that is equivalent to the given expression.

Solution:

According to the property of summation:

$\sum\limits_(n=0)^(k)Cn=C\sum\limits_(n=0)^(k)n$

Where, C is a constant.

We have,

$\sum\limits_(n=0)^(27)8n$

Using the above mentioned property of summation, we get

$\sum\limits_(n=0)^(27)8n=8\sum\limits_(n=0)^(27)n$

The expression
$8\sum\limits_(n=0)^(27)n$ is equivalent to the given expression.

Therefore, the correct option is C.
