Question

I don't know the answer pls help me out​

Answer 1

Answer:

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