Ответ:

1)

а)

$- \frac{35}{2} a {}^{3} b {}^{3} c {}^{7}$

б)

$x {}^{3} y$

в)

$- 8m {}^{2} n {}^{4}$

г)

$6.75p {}^{5} q {}^{2}$

2)

1)

$- \frac{1}{125} k {}^{6} l {}^{12}$

2)

$0.0001a {}^{2} b {}^{14} c {}^{6}$

Объяснение:

1)

а)

$2 \frac{1}{2} a {}^{2} b {}^{3} c {}^{4} \times ( - 7)ac {}^{3} = \\ = \frac{5}{2} \times ( - 7) \times a {}^{2 + 1} \times b {}^{3} \times c {}^{4 + 3} = \\ = - \frac{35}{2} a {}^{3} b {}^{3} c {}^{7}$

б)

$- 5x {}^{2} y \times ( - \frac{1}{5} )x = \\ = - 5 \times ( - \frac{1}{5} ) \times x {}^{2 + 1} \times y = \\ = x {}^{3} y$

в)

$mn {}^{3} \times ( - 8)mn = \\ = ( - 8) \times m {}^{1 + 1} \times n {}^{3 + 1} = \\ = - 8m {}^{2} n {}^{4}$

г)

$- 2.25p {}^{3} q {}^{2} \times ( - 3)p {}^{2} = \\ = ( - 2.25) \times ( - 3) \times p {}^{3 + 2} \times q {}^{2} = \\ = 6.75p {}^{5} q {}^{2}$

2)

1).

$( - \frac{1}{5} k {}^{2} l {}^{4} ) {}^{3} = ( - \frac{1}{5} ) {}^{3} \times \\ \times k {}^{2 \times 3} \times l {}^{4 \times 3} = \\ = - \frac{1}{125} k {}^{6} l {}^{12}$

2)

$( - 0.01ab {}^{7} c {}^{3} ) {}^{2} = \\ = ( - 0.01) {}^{2} \times a {}^{2} \times b {}^{7 \times 2} \times c {}^{3 \times 2} = \\ = 0.0001a {}^{2} b {}^{14} c {}^{6}$
