a)
[tex] =(ab) \: . \: ( - 2a {}^{2} )[/tex]
[tex] = - ab \: . \: 2a {}^{2} [/tex]
[tex] = - 2a {}^{3} b[/tex]
b)

[tex] = - 3m {}^{2} \: . \: mx[/tex]
[tex] = - 3m {}^{3} x[/tex]
c)

[tex] = - 6ab {}^{2} a {}^{2} b[/tex]
[tex] = - 6a {}^{3} b {}^{3} [/tex]
d)
[tex] = (5m {}^{2} y) \: . \: ( - m {}^{2} )[/tex]
[tex] = - 5m {}^{2} ym {}^{2} [/tex]
[tex] = - 5m {}^{4} y[/tex]
e)

[tex] = 7a {}^{4} y \: . \: y {}^{3} a {}^{3} y[/tex]
[tex] = 7a {}^{7} y {}^{5} [/tex]
f)
[tex] = (2a {}^{2} b) \: . \: ( - ab) \: . \: ( - a {}^{2} )[/tex]
[tex] = 2a {}^{2} baba {}^{2} [/tex]
[tex] = 2a {}^{5} b {}^{2} [/tex]
2.
a)
[tex]\frac{ - 8a {}^{3}x {}^{2} }{2a {}^{2}x } = \frac{ - 4x {}^{3}x {}^{2} }{a {}^{2} x} = \frac{ - 4ax {}^{2} }{x} = - 4ax[/tex]
b)
[tex] \frac{16amx {}^{2} }{ - 8ax} = \frac{16mx {}^{2} }{ - 8x} = \frac{ - 2mx {}^{2} }{x} = - 2mx[/tex]
c)
[tex] \frac{ - 12ab {}^{2} }{6ab} = \frac{ - 12b {}^{2} }{6b} = \frac{ - 2b {}^{2} }{b} = - 2b[/tex]
d)
[tex] \frac{9a {}^{4} x {}^{2} }{3a {}^{2} x {}^{2} } = \frac{9a {}^{4} }{3a {}^{2} } = \frac{3a {}^{4} }{a {}^{2} } = 3a {}^{2} [/tex]
e)
[tex] \frac{ - 14a {}^{2}b }{7a {}^{3} b {}^{2} } = \frac{ - 2a {}^{2} b}{a {}^{3}b {}^{2} } = \frac{ - 2ab}{ab {}^{2} } = \frac{ - 2}{ab} = - \frac{2}{ab} [/tex]
f)
[tex] \frac{9axy}{ - 9a {}^{3} x {}^{2} } = \frac{ - axy}{a {}^{3} x {}^{2} } = \frac{ - xy}{a {}^{2}x {}^{2} } = \frac{ - y}{a {}^{2}x } = - \frac{y}{a {}^{2} x} [/tex]
g)
[tex] \frac{12xm {}^{3} }{ - 2x m{}^{4} } = \frac{12m {}^{3} }{ - 2m {}^{4} } = \frac{ - 6m {}^{3} }{m {}^{4} } = \frac{ - 6}{m} = - \frac{6}{m} [/tex]
