Ответ:

$0.6 \sqrt{50} - \frac{2}{3} \sqrt{18} + 1.5 \sqrt{8} = 0.6 \sqrt{25 \times 2} - \frac{2}{3} \sqrt{9 \times 2} + 1.5 \sqrt{4 \times 2} = 0.6 \times 5 \sqrt{2} - \frac{2}{3} \times 3 \sqrt{2} + 1.5 \times 2 \sqrt{2} = 3 \sqrt{2} - 2 \sqrt{2} + 3 \sqrt{2} = \sqrt{2} + 3 \sqrt{2} = 4 \sqrt{2}$
