1) $- 2.5m( - 2) {m}^{3} {m}^{2}$
2)$abc12 {b}^{2} {c}^{3}$
3)$- 4xy( - 3) {x}^{2} y( - 2)x {y}^{4}$
4)$\frac{2}{3} a {x}^{ 3} 12a {c}^{2} x$

Answer 1

1)
$- 2.5m \times ( - 2) {m}^{3} {m}^{2} = 5 {m}^{ 1 + 3 + 2} = 5 {m}^{6}$
2)
$abc \times 12 {b}^{2} {c}^{3} = 12a {b}^{1 + 2} {c}^{1 + 3} = 12a {b}^{3} {c}^{4}$
3)
$- 4xy \times ( - 3) {x}^{2} \times ( - 2)x {y}^{4} = - 24 {x}^{1 + 2 + 1} {y}^{1 + 4} = - 24 {x}^{4} {y}^{5}$
4)
$\frac{2}{3} a {x}^{3} \times 12a {c}^{2} x = 8 {a}^{1 + 1} {c}^{2} {x}^{3 + 1} = 8 {a}^{2} {c}^{2} {x}^{4}$
