Hi...☺

Here is your answer...✌

 \frac{5 + 2 \sqrt{3} }{7 + 4 \sqrt{3} }  \\

On rationalising the denominator,
We get

 \frac{5 + 2 \sqrt{3} }{7 + 4 \sqrt{3} }  =  \frac{5 + 2 \sqrt{3} }{7 + 4 \sqrt{3} }  \times  \frac{7 - 4 \sqrt{3} }{7 - 4 \sqrt{3} }  \\  \\  =  \frac{35 - 20 \sqrt{3}  + 14 \sqrt{3}  -8 \times 3 }{ {7}^{2} -  {(4 \sqrt{3}) }^{2}  }  \\   \\ =  \frac{35 - 6 \sqrt{3}  - 24}{49 - 48}  \\  \\  =  \frac{11 - 6 \sqrt{3} }{1}  \\  \\  = 11 - 6 \sqrt{3}
