Answer 1

1/3-√2
1/3-1.4
.33-1.4
=1.7

Answer 2

$\frac{1}{3 - \sqrt{2}} = 0.6$        $\frac{1}{3 + 2\sqrt{2}} = 0.17$

Step-by-step explanation:

Given Data

√2 = 1.4

√3 = 1.7

To Find :

$1. \frac{1}{3 - \sqrt{2}}$  

$2. \frac{1}{3 + 2\sqrt{2}}$

$1. \ \frac{1}{3 - \sqrt{2}} = \frac{1}{ 3 - 1.4}$

$\frac{1}{3 - \sqrt{2}} = \frac{1}{1.6}$

$\frac{1}{3 - \sqrt{2}} = 0.6$

$2. \ \frac{1}{3 + 2\sqrt{2}} = \frac{1}{3 + 2 (1.4)}$

$\frac{1}{3 + 2\sqrt{2}} = \frac{1}{3 + 2.8}$

$\frac{1}{3 + 2\sqrt{2}} = \frac{1}{5.8}$

$\frac{1}{3 + 2\sqrt{2}} = 0.17$
