$4 \sqrt{2}$ $4sqrt2$

Explanation:

$using the law of radicals$ $"using the "color(blue)"law of radicals"$

$∙ x \sqrt{a} \times \sqrt{b} \Leftrightarrow \sqrt{a b}$ $•color(white)(x)sqrtaxxsqrtbhArrsqrt(ab)$

$\sqrt{8} \times \sqrt{4} = \sqrt{8 \times 4} = \sqrt{32}$ $sqrt8xxsqrt4=sqrt(8xx4)=sqrt32$

$\sqrt{32} = \sqrt{16 \times 2} = \sqrt{16} \times \sqrt{2} = 4 \sqrt{2}$ $sqrt32=sqrt(16xx2)=sqrt16xxsqrt2=4sqrt2$
