Question

Which expression is equivalent to 27 Σ 8n? N=0 hurry please my life depends on it

Answer 1

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.
