Answer 2

$Given \: \frac{1}{(3+\sqrt{2}} + \frac{1}{(3-\sqrt{2})}$

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

$= \frac{6}{3^{2} - (\sqrt{2})^{2}}$

$= \frac{ 6}{9 - 2}$

$= \frac{6}{7}$

Therefore.,

$\red{\frac{1}{(3+\sqrt{2}} + \frac{1}{(3-\sqrt{2})}}$

$\green {= \frac{6}{7} }$
