​

Answer 1

Ответ:

$5 {a}^{6} \times ( - 3a {}^{2} b {)}^{2} = 5 {a}^{6} \times 9 {a}^{4} {b}^{2} = 45 {a}^{10} {b}^{2}$

$( - {x}^{4} {y}^{3} {)}^{7} \times 8 {x}^{2} {y}^{5} = {x}^{28} {y}^{21} \times 8 {x}^{2} {y}^{5} = 8 {x}^{30} {y}^{26}$

$( - 0.1 {a}^{2} b {c}^{5} {)}^{2} \times 100 {c}^{4} = 0.01 {a}^{4} {b}^{2} {c}^{10} \times 100 {c}^{4} = {a}^{4} {b}^{2} {c}^{14}$
