Question

please help its urgent ​

Answer 1

Step-by-step explanation:

$\frac{5 + 3 \sqrt{3} }{7 +4 \sqrt{3} } = a + b \sqrt{3} \\ \frac{5 + 3 \sqrt{3} }{49 + 16 \times 3} (7 - 4 \sqrt{3} ) = a + b \sqrt{3} \\ \frac{5 + 3 \sqrt{3} }{97} (7 - 4 \sqrt{3} ) = a + b \sqrt{3} \\ (5 + 3 \sqrt{3} )(7 - 4 \sqrt{3} ) = 97(a + b \sqrt{3} )$

Answer 2
