Answer 1

Respuesta:

A)

$2ab + ( - 3 {a}^{2} b) + ( - 7 {a}^{2}b) + ( - 8ab) \\ 2ab - 8ab - 3 {ab}^{2} - 7 {a}^{2} b \\ - 6ab - 10 {a}^{2} b$

C)

$- \frac{2}{3} {m}^{2} n + ( - \frac{3}{2}m {n}^{2} ) + ( - \frac{7}{6} {m}^{2} n) + ( - \frac{1}{2} {m}^{2} n) + m {n}^{2} \\ - \frac{2}{3} {m}^{2} n - \frac{7}{6} {m}^{2} n- \frac{1}{2} {m}^{2} n + m {n}^{2} - \frac{3}{2}m {n}^{2} \\ - \frac{14}{6} {m}^{2} n - \frac{1}{2} m {n}^{2} \\ - \frac{7}{6} {m}^{2} n - \frac{m {n}^{2}}{2}$
