$9 \sqrt{2}$ $9sqrt2$

rewrite the roots as the same square root where possible

$3 \sqrt{8} + 3 \sqrt{2}$ $3sqrt8+3sqrt2$

$= 3 \sqrt{4 \times 2} + 3 \sqrt{2}$ $=3sqrt(4xx2)+3sqrt2$

$= 3 \times 2 \sqrt{2} + 3 \sqrt{2}$ $=3xx2sqrt2+3sqrt2$

$= 6 \sqrt{2} + 3 \sqrt{2}$ $=6sqrt2+3sqrt2$

$= 9 \sqrt{2}$ $=9sqrt2$
