Answer:

$8 \sqrt{45} - 8 \sqrt{20} + 4 \sqrt{8} \\ \\ 8 \sqrt{3 \times 3 \times 5} - 8 \sqrt{2 \times 2 \times 5} + 4 \sqrt{2 \times 2 \times 2} \\ \\ 8 \times 3 \sqrt{5} - 8 \times 2 \sqrt{5} + 4 \times 2 \sqrt{2} \\ \\ 24 \sqrt{5} - 16 \sqrt{5} + 8 \sqrt{2} \\ \\ 8 \sqrt{5} + 8 \sqrt{2} \\ \\ 8( \sqrt{5} + \sqrt{2} )$
