Answer:

heya mate ☺

$4 \sqrt{50} - \sqrt{128} + \sqrt{18} \\ \\ = 4 \sqrt{25 \times 2} - \sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2} + \sqrt{9 \times 2} \\ \\ = 4 \times 5 \sqrt{2} - 2 \times 2 \times 2 \sqrt{2} + 3 \sqrt{2} \\ \\ = 20 \sqrt{2} - 8 \sqrt{2} + 3 \sqrt{2} \\ \\ = 12 \sqrt{2} + 3 \sqrt{2} \\ \\ = 15 \sqrt{2}$
