Answer 2

Answer:

heya mate ☺

$\sqrt{32} + 2 \sqrt{8} - 4 \sqrt{128} \\ = \sqrt{2 \times 2 \times 2 \times 2 \times 2} +2 \sqrt{8} - 4 \sqrt{128} \\ = 2 \times 2 \sqrt{2} + 2 \sqrt{2 \times 2 \times 2} - 4 \sqrt{128} \\ = 4 \sqrt{2} + 2 \times 2 \sqrt{2} - 4 \sqrt{128} \\ = 4 \sqrt{2 } + 4 \sqrt{2} - 4 \sqrt{128} \\ = 8 \sqrt{2} - 4 \sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2} \\ = 8 \sqrt{2} - 4 \times 2 \times 2 \times 2 \sqrt{2} \\ = 8 \sqrt{2} - 32 \sqrt{2} \\ = - 24 \sqrt{2}$
