Answer 1

PREGUNTA 1

$\frac{ - 20m {n}^{4} {x}^{2} {y}^{3} }{4nx {y}^{3} } \\ \frac{ - 5m {n}^{4} {x}^{2} }{nx} \\ \frac{ - 5m {n}^{3} {x}^{2} }{x} \\ - 5m {n}^{3} x$

PREGUNTA 2

$\frac{3 {a}^{3} - 6 {a}^{2}b + 9a {b}^{2} }{ - 2 {a}^{2} {b}^{4} } \\ \frac{a \times (3 {a}^{2} - 6ab + 9 {b}^{2} ) }{ - 2 {a }^{2} {b}^{4} } \\ \frac{3 {a}^{2} - 6ab + 9 {b}^{2} }{ - 2a {b}^{4} } \\ - \frac{3 {a}^{2} - 6ab + 9 {b}^{2} }{2a {b}^{4} }$

PREGUNTA 3

$\frac{2 {x}^{m} - 3 {x}^{m + 2} + 6 {x}^{m + 4} }{3 {x}^{m} } \\ \frac{ {x}^{m} \times (2 - 3 {x}^{2} + 6 {x}^{4} ) }{3 {x}^{m} } \\ \frac{2 - 3 {x}^{2} + 6 {x}^{4} }{3} \\ \frac{6 {x}^{4} - 3 {x}^{2} + 2 }{3} \\ 2 {x}^{4} - {x}^{2} + \frac{2}{3}$

PREGUNTA 4

$\frac{ {a}^{2} + 2a - 3 }{a + 3} \\ \frac{(a + 3) \times (a - 1)}{a + 3} \\ a - 1$

PREGUNTA 5

$\frac{ - 8 {x}^{2} + 12xy - 4 {y}^{2} }{y - x} \\ \frac{ - 4 \times (2 {x}^{2} - 3xy + {y}^{2}) }{ - (x - y)} \\ \frac{ - 4 \times (2x - y) \times (x - y)}{ - (x - y)} \\ 4 \times (2x - y) \\ 8x - 4y$

PREGUNTA 6

$\frac{ {x}^{3} - 4x - 1 }{x + 1} \\ {x}^{2} - x - 3 + \frac{2}{x + 1}$

PREGUNTA 7

$\frac{ {m}^{5} + m}{m + 2} \\ {m}^{4} - 2 {m}^{3} + 4 {m}^{2} - 8m + 17 + \frac{ - 34}{m + 2}$
