Ответ:

$10 {a}^{3} {c}^{4} {b}^{2} \times ...$

1

$... \times 1.6xy = 16 {a}^{3} {c}^{4} {b}^{2} xy$

2

$... \times 2 \frac{1}{5} {a}^{3} {c}^{4} {b}^{5} = 22 {a}^{6} {c}^{8} {b}^{7}$

3

$... \times - 10a {b}^{2} = - 100 {a}^{4} {c}^{4} {b}^{4}$

4

$... \times - 3b = - 30 {a}^{3} {c}^{4} {b}^{3}$
