Question

386 надо решить помогите

Answer 1

Ответ:

1.

$1.6 \times {( - 5)}^{2} = 1.6 \times 25 = 40$

$1.6 \times {0}^{2} = 0$

$1.6 \times {( - 1)}^{2} = 1.6 \times 1 = 1.6$

2

$5 \times {0.2}^{2} \times 0.1 = 5 \times0.04 \times 0.1 = 0.2 \times 0.1 = 0.02$

$5 \times ( { - 0.4}^{2}) \times 2 = 5 \times 0.16 \times 2 = 1.6$
