Answer 1

$3 \times 2 + 7 + 3 - 2 \times {4}^{2} \times \sqrt{4} + 20 - 100 = \\ 3 \times 2 + 7 + 3 - 2 \times {4}^{2} \times 2 + 20 - 100 = \\ 3 \times 2 + 7 + 3 - 2 \times 16 \times 2 + 20 - 100 = \\ 6 + 7 + 3 - 32 \times 2 + 20 - 100 = \\ 6 + 7 + 3 -64 + 20 - 100 = \\ 13 + 3 - 64 + 20 - 100 = \\ 16 - 64 + 20 - 100 = \\ - 48 + 20 - 100 = \\ - 28 - 100 = \\ - 128$
