$40 \sqrt{14}$ $40sqrt(14)$

First, you would simplify $\sqrt{8}$ $sqrt(8)$ to $2 \sqrt{2}$ $2sqrt(2)$ , so the expression would look like:

$5 \times 2 \sqrt{2} \times 4 \sqrt{7}$ $5 xx 2sqrt(2) xx 4sqrt(7)$

Then, simplify further so the expression would look like:

$5 \times 2 \times 4 \sqrt{2 \times 7}$ $5 xx 2 xx 4sqrt(2 xx 7)$

Multiply and you will get

$5 \times 2 \times 14 \sqrt{14}$ $5 xx 2 xx 14sqrt(14)$

Simplify that further and you'll get

$40 \sqrt{14}$ $40sqrt(14)$
