Answer 1

Answer:

$\frac{ \sqrt{19} + \sqrt{12} }{7} .$

Step-by-step explanation:

$\frac{1}{ \sqrt{19} - \sqrt{12} } = \frac{1}{ \sqrt{19} - \sqrt{12} } \times \frac{ \sqrt{19} + \sqrt{12} }{ \sqrt{19} + \sqrt{12} } \\ \\ = \frac{ \sqrt{19} + \sqrt{12} }{19 - 12} \\ \\ = \frac{ \sqrt{19} + \sqrt{12} }{7} .$
