Answer 2

$Given \: 3\sqrt{61} + 3\sqrt{25} + 3\sqrt{8}$

$= 3\sqrt{61} + 3\sqrt{5^{2}} + 3\sqrt{2^{2} \times 2}$

$= 3\sqrt{61} + 3\times 5 + 3\times 2\times \sqrt{2}$

$= 3\sqrt{61} + 15 + 6\sqrt{2}$

Therefore.,

$\red {3\sqrt{61} + 3\sqrt{25} + 3\sqrt{8}}$

$\green { = 3\sqrt{61} + 15 + 6\sqrt{2} }$
