Answer 1

Answer:

a= 11

b= -6

Step-by-step explanation:

$\frac{5 + 2 \sqrt{3} }{7 + 4 \sqrt{3} } \times \frac{7 - 4 \sqrt{3} }{7 - 4 \sqrt{3} }$

(Rationalised)

$\frac{35 - 20 \sqrt{3} + 14 \sqrt{3} - 24}{49 - 48}$

$\frac{11 - 6 \sqrt{3} }{1}$

$11 + ( - 6 \sqrt{3} )$

Let "11+(-6√3)" the value of a+b√3

a= 11

b= -6
