Hello friend

Your answer is given below :

 =  >  \frac{7 + 3 \sqrt{5} }{7 - 3 \sqrt{5} }  \\  \\  =  >  \frac{7 + 3 \sqrt{5} }{7 - 3 \sqrt{5} }  \times   \frac{7 + 3 \sqrt{5} }{7 + 3 \sqrt{5} }  \\  \\  =  >  \frac{{(7 + 3 \sqrt{5} )}^{2} }{ {7}^{2}  -  {(3 \sqrt{5}) }^{2} }  \\  \\  =  > \frac{49 + 45 + 42 \sqrt{5} }{49 - 45}  \\  \\  =  >  \frac{94 + 42 \sqrt{5} }{4}

I hope it will help you
