Question

Fast And CORRECT...And you'll be the BRAINLIEST

Answer 1

Answer:

a = 11 , b = 6

Step-by-step explanation:

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

a = 11 , b = 6
