SOLUTION:

$\sf \: formula \: used \ratio$

$\sf \: \sqrt{ab} = \sqrt{a} \times \sqrt{b} \\ \\ \sf \: \: \sqrt{ \frac{a}{b} } = \frac{ \sqrt{a} }{ \sqrt{b} }$

EXPLANATION:

$(3 \sqrt{2} + 7 \sqrt{3} ) + ( \sqrt{2} - 5 \sqrt{3} \\ \\ = (3 \sqrt{2} + \sqrt{2} ) + (7 \sqrt{3} - 5 \sqrt{3}) \\ \\ = (3 + 1) \sqrt{2} + (7 - 5) \sqrt{3} \\ \\ = (4 \sqrt{2} + 2 \sqrt{3} )$
