Answer:

12\sqrt{6} + 8\sqrt{15} + 12 + 4\sqrt{10}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Given

(4\sqrt{3} + 2\sqrt{2} )(3\sqrt{2} + 2\sqrt{5} )

Each term in the second factor is multiplied by each term in the first factor, that is

4\sqrt{3} (3\sqrt{2} + 2\sqrt{5} ) + 2\sqrt{2} (3\sqrt{2} + 2\sqrt{5} ) ← distribute both parenthesis

= 12\sqrt{6} + 8\sqrt{15} + 12 + 4\sqrt{10}
