$= 20 \sqrt{2}$ $=20sqrt2$

Explanation:

It will help to realise that $\sqrt{2}$ $sqrt2$ can be used as like terms.

In the same way that $2 \times 7 + 3 \times 7$ $2 xx 7 + 3 xx 7$ can be written as $5 \times 7$ $5 xx 7$ ,
$2 \sqrt{2} + 3 \sqrt{2} = 5 \sqrt{2}$ $2sqrt2 + 3sqrt2= 5sqrt2$

$4 (2 \sqrt{2} + 3 \sqrt{2}) = 4 (5 \sqrt{2})$ $4(2sqrt2 + 3sqrt2) = 4(5sqrt2)$

$= 20 \sqrt{2}$ $=20sqrt2$
