Answer 2

$\huge{\underline{\tt Solution:-}}$

$\\ \tt \longmapsto \: (2 + \sqrt{3} )(3 + \sqrt{5} ) \\ \\ \tt \longmapsto \: 2(3 + \sqrt{5} ) + \sqrt{3} (3 + \sqrt{5} ) \\ \\ \tt \longmapsto \: 6 + 2 \sqrt{5} + 3 \sqrt{3} + \sqrt{3} \sqrt{5} \\ \\ \tt \longmapsto \: 6 + 2 \sqrt{5} + 3 \sqrt{3} + \sqrt{3 \times 5} \\ \\ \tt \longmapsto \: 6 + 2 \sqrt{5} + 3 \sqrt{3} + \sqrt{15}$

Hence forth

(2+√3)(3+√5)=6+2√5+3√3+√15
