Hey friend !!!!

•°• Here's your answer •°•

 \frac{7 + \sqrt{5} }{7 - \sqrt{5} } - \frac{7 - \sqrt{5} }{7 + \sqrt{5} } \\ \\ \frac{7 + \sqrt{5} }{7 - \sqrt{5} } \times \frac{7 + \sqrt{5} }{7 + \sqrt{5} } - \frac{7 - \sqrt{5} }{7 + \sqrt{5} } \times \frac{7 - \sqrt{5} }{7 - \sqrt{5} } \\ \\ \frac{ {(7 + \sqrt{5}) }^{2} }{ {7}^{2} - { \sqrt{5} }^{2} } - \frac{ {(7 - \sqrt{5}) }^{2} }{ {7}^{2} - { \sqrt{5} }^{2} } \\ \\ \frac{49 + 5 + 14 \sqrt{5} }{44} - \frac{49 + 5 - 14 \sqrt{5} }{44} \\ \\ \frac{49 + 5 + 14 \sqrt{5} - 49 - 5 + 14 \sqrt{5} }{44} \\ \\ \frac{28 \sqrt{5} }{44}


After cutting you will get

7root 5/11
