​

Answer 1

See the image for answer.

Answer 2

(1)

$\sqrt{72} \times \sqrt{338} \\ \\ = > \sqrt{72 \times 338} = \sqrt{24336} = \sqrt{2 \times 2 \times 2 \times 2 \times 3 \times 3 \times 13 \times 13} \\ \\ = > 2 \times 2 \times 3 \times 13 = 156$

(2)

$\sqrt{108} \times \sqrt{48} \\ \\ = > \sqrt{5184} = \sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3 \times 3 \times 3} \\ \\ = > 2 \times 2 \times 2 \times 3 \times 3 = 72$
