Answer 1

Hii
Nice question

Question:-

1 / (√7 + √3 - √2)

Answer:-

$= \frac{1}{ \sqrt{7} } + \frac{1}{ \sqrt{3} } - \frac{1}{ \sqrt{2} } \\ = ( \frac{1}{ \sqrt{7} } \times \frac{ \sqrt{7} }{ \sqrt{7} } ) + ( \frac{1}{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } ) - \frac{1}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } \\ = \frac{ \sqrt{7} }{ { (\sqrt{7}) }^{2} } + \frac{ \sqrt{3} }{ ({ \sqrt{3} )}^{2} } - \frac{ \sqrt{2} }{ { (\sqrt{2}) }^{2} } \\ = \frac{ \sqrt{7} }{7} + \frac{ \sqrt{3} }{3} - \frac{ \sqrt{2} }{2} \\ = \frac{6 \sqrt{7} + 14 \sqrt{3} - 21 \sqrt{2} }{42}$
