Chapter 8.9, Problem 17WE

To determine

To find: the value of square root by using the table.

Answer to Problem 17WE

The value of square root is $2.7614$ .

Explanation of Solution

Given information:

The square root is $\sqrt{7.63}$ .

Calculation: to find the value of $\sqrt{7.63}$ ,

$x$	$\sqrt{x}$
$7.6$	$2.756$
$7.63$	$\sqrt{7.63}$
$7.7$	$2.774$

Now, the difference,

  $\begin{array}{l}d=\frac{0.03}{.1}\left(0.018\right)\\ d=0.0054\text{ [simplify]}\end{array}$

Now, to find the value of square root,

  $\begin{array}{l}\sqrt{7.63}=2.756+0.0054\\ \sqrt{7.63}=2.7614\text{ [add]}\end{array}$

Thus, The value of square root is $2.7614$ .
