Question

3+square root of 7 divide by 3- square root of 7=a+B into square root of 7​

Answer 1

$\frac{3 + \sqrt{7} }{3 - \sqrt{7} } \times \frac{3 + \sqrt{7} }{3 + \sqrt{7} } \\ \frac{ {(3 + \sqrt{7)} }^{2} }{ {3}^{2} - \sqrt{ {(7)}^{2} } } \\ \frac{9 + 7 + 6 \sqrt{7} }{2} \\ \frac{16 + 6 \sqrt{7} }{2} \\ \frac{2(8 + 3) \sqrt{7} }{2} \\ 8 + 3 \sqrt{7}$
