Answer 1

Explicación paso a paso:

$4 \sqrt{7} \times 3 \sqrt{8} = 4 \times 3 \times \sqrt[]{7 \times 8} = 12 \sqrt{56} = 12 \sqrt{4 \times 14} = 12 \times 2 \sqrt{14} = 24 \sqrt{14}$

$3 \sqrt{4x} \times \frac{ \sqrt{2 {x}^{2} } }{3} \times \frac{ \sqrt{x} }{2} = \sqrt{x} \times x \sqrt{2} \times \sqrt{x} = {x}^{2} \sqrt{2}$

$\sqrt{3} (2 \sqrt{6} + 3 \sqrt{5} ) = 2 \sqrt{3 \times 6} + 3 \sqrt{3 \times 5} = 2 \sqrt{18} + 3 \sqrt{15}$
