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.
