Answer 1

hey! here is the answer..... hope it helps u

Answer 2

$Given : \frac{5 + \sqrt{3} }{7 - 4 \sqrt{3} }$

$\frac{(5 + \sqrt{3})(7 + 4 \sqrt{3}) }{(7 - 4 \sqrt{3} )(7 + 4 \sqrt{3} )}$

$\frac{5 * 7 + 5 * 4 \sqrt{3} + \sqrt{3} * 7 + \sqrt{3} * 4 \sqrt{3} }{(7)^2 - (4 \sqrt{3} )^2}$

$\frac{35 + 27 \sqrt{3} + 12}{49 - 48}$

$\frac{47 + 27 \sqrt{3} }{1}$

$47 + 27 \sqrt{3}$


Now,

$a + \sqrt{3} b = 47 + 27 \sqrt{3}$


Therefore a = 47, b = 27.


Hope this helps!
