Question

Root 3 + root 7 divided by root 3 - root 7

Answer 1

√3+√7/√3-√7
it give the answer -4.79

Answer 2

Let see your answer !!!!!

$\frac{ \sqrt{3} + \sqrt{7} }{ \sqrt{3} - \sqrt{7} } \\ \\ = \frac{( \sqrt{3} + \sqrt{7}) \times ( \sqrt{3} + \sqrt{7} ) }{( \sqrt{3} - \sqrt{7} ) \times ( \sqrt{3} + \sqrt{7} )} \\ \\ = \frac{( \sqrt{3} + \sqrt{7}) ^{2} }{( \sqrt{3}) ^{2} - ( \sqrt{7}) ^{2} } \\ \\ = \frac{( \sqrt{3} ) ^{2} + ( \sqrt{7}) ^{2} + 2 \times \sqrt{3} \times \sqrt{7} }{3 - 7} \\ \\ = \frac{3 + 7 + 2 \sqrt{21} }{ - 4} \\ \\ = \frac{10 + 2 \sqrt{21} }{ - 4} \\ \\ = \frac{10}{ - 4} + \frac{2 \sqrt{21} }{ - 4} \\ \\ = \frac{ - 5}{2} + ( \frac{ - \sqrt{21} }{2} ) \\ \\ = \frac{ - 5 - \sqrt{21} }{2}$
