 \frac{5 +  \sqrt{3} }{7 - 4 \sqrt{3} }  = 94a + 3 \sqrt{3} b \\ 94a + 3 \sqrt{3} b =  \frac{(5 +  \sqrt{3})(7 + 4 \sqrt{3} )}{(7 - 4 \sqrt{3} )(7 + 4 \sqrt{3}) }   \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: =  \frac{35 + 7 \sqrt{3}  + 20 \sqrt{3}  + 12}{49 - 48}  \\   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  =  \frac{47 + 27 \sqrt{3} }{1}  \\ 94a = 47 \\ a =  \frac{1}{2}  \\ 3 \sqrt{ 3} b = 27 \sqrt{3}  \\ b = 9
