Chapter 11.4, Problem 77E

To determine

To calculate:

Sum of the given function.

  ${\displaystyle \sum _{k=1}^{11}16}$

Answer to Problem 77E

Sum of given function is $176$ .

Explanation of Solution

Given information:

  ${\displaystyle \sum _{k=1}^{11}16}$

Calculation:

The property of sum that ${\displaystyle \sum _{i=1}^{n}c=cn}$ ,

Where,

  $c=$ constant.

Now here substitute $16$ for $c$ , $10$ for $n$ and $k$ for $i$ in ${\displaystyle \sum _{i=1}^{n}c=cn}$ .

So function will be,

  $\begin{array}{l}{\displaystyle \sum _{k=1}^{11}16}=16.11\\ =176\end{array}$

so sum is $176$ .
