Answer 1

Answer:

3.5 and 1.5

Step-by-step explanation:

Rationalising the given term, we get,

$\frac{3 + \sqrt{5} }{3 - \sqrt{5} } = \frac{3 + \sqrt{5} }{3 - \sqrt{5} } \times \frac{3 + \sqrt{5} }{3 + \sqrt{5} }$

$= \frac{9 + 5 + 6 \sqrt{5} }{9 - 5} = \frac{14 + 6 \sqrt{5} }{4}$

$= \frac{7}{2} + \frac{3}{2} \sqrt{5}$

$a = \frac{7}{2} = 3.5$

$b = \frac{3}{2} = 1.5$
