Answer:

144 $\sqrt{2}$

Step-by-step explanation:

We can simplify the product using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

simplify $\sqrt{64}$ = 8

simplify $\sqrt{8}$ = $\sqrt{4(2)}$ = $\sqrt{4}$ × $\sqrt{2}$ = 2 $\sqrt{2}$

The product can now be expressed as

3 × 8 × 3 × 2 × $\sqrt{2}$

= 144 $\sqrt{2}$
