Answer 1

$8 {a}^{2} b \times ( - \frac{1}{4} a {b}^{6}) \times ( - \frac{1}{2} {b}^{5} {a}^{3} ) =8 {a}^{2} b \times ( - \frac{1}{4} a {b}^{6}) \times ( - \frac{1}{2} {a}^{3} {b}^{5} ) = 2 {a}^{2} ba {b}^{6} \times \frac{1}{2} {a}^{3} {b}^{5} = 2 {a}^{2} ba {b}^{6}{a}^{3}{b}^{5} = {a}^{6} {b}^{12}$
