Answer 1

Answer:

a = 75, b = 15

Step-by-step explanation:

First we have to rationalise the denominator of the fraction in LHS.

$\frac{5 + \sqrt{3} }{7 - 4\sqrt{4} } \\\\= \frac{(5 + \sqrt{3})(7 + 4\sqrt{4})}{(7 - 4\sqrt{4})(7 + 4\sqrt{4})} \\\\= 35 + 20\sqrt{4} + 15\sqrt{3}$

a = 35 + 40 = 75

b = 15
