Объяснение:

$1)3 {a}^{2} {b}^{3} \times 4a {b}^{2} = 12 {a}^{3} {b}^{5}$

$2)6b \times 0.5c = 3bc$

$3)3a \times 7a = 21 {a}^{2}$

$4)9x {y}^{2} \times ( - 2) {x}^{3}y = - 18 {x}^{4} {y}^{3}$

$5) - \frac{1}{6} m {n}^{2} \times 9 {m}^{3}n \times 2 {m}^{2} n = - 3 {m}^{6} {n}^{4}$

$6) - 5a \times 2a \times ( - 3) {b}^{3} = 30 {a}^{2} {b}^{3}$
