Выполните деление многочлена на одночлен: (4а³b5-8a²b³):(2ab³)=? (15mp-3np):(3p)=?...

Решите задачу:

$\frac{4 {a}^{3} {b}^{5} - 8 {a}^{2} {b}^{3} } {2 {ab}^{3} } = \frac{2 {a}^{2} {b}^{3}(2 {ab}^{2} - 4) }{2 {ab}^{3} } = \\ = a(2 {ab}^{2} - 4) = 2 {a}^{2} {b}^{2} - 4a$

$\frac{15mp - 3np}{3p} = \frac{3p(5m - n)}{3p} = 5m -n$

$\frac{(xy - {y}^{2}) }{ - y} = - \frac{y(x - y)}{y} = - x + y$

$\frac{ - 26 {c}^{5} {d}^{4} + 13 {c}^{4} {d}^{3} }{ - 13 { {c}^{4} {d}^{3} }^{} } \\ = \frac{ - 13 {c}^{4} {d}^{3} (2cd - 1) }{ - 13 {c}^{4} {d}^{3} } = 2cd - 1$
