Answer 1

Answer:

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