Answer 2

$= 3 \sqrt{32} - 2 \sqrt{50} + 4 \sqrt{128} - 20 \sqrt{18} \\ =( 3 \times 4 \sqrt{2} - 2 \times 5 \sqrt{2}) +( 4 \times 8 \sqrt{2} ) - 20 \times 3 \sqrt{2} \\ = 12 \sqrt{2} - 10 \sqrt{2} + 32 \sqrt{2} - 60 \sqrt{2} \\ = 44 \sqrt{2} - 70 \sqrt{2} \\ = - 26 \sqrt{2} \\ = - 26 \times 1.414 \\ = - 36.764$
