Answer 1

Step-by-step explanation:

$\frac{7}{3 + \sqrt{2} } \times \frac{3 - \sqrt{2} }{3 - \sqrt{2} }$

$\frac{7 \times 3 - \sqrt{2} }{(3 + \sqrt{2}) \times( 3 - \sqrt{2}) }$

$\frac{21 - 7 \sqrt{2} }{ {3}^{2} - { \sqrt{2} }^{2} }$

$\frac{21 - 7 \sqrt{2} }{9 - 2}$

$\frac{21 - 7 \sqrt{2} }{7}$

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