Answer 1

Ответ:

232.

1)

$(0.3 {a}^{2} )( \frac{1}{4} {b}^{3} ) = (\frac{3}{10} {a}^{2} )( \frac{1}{4} {b}^{3} ) = \frac{3}{40} {a}^{2} {b}^{3}$

2)

$( - 8 {m}^{3} )(0.25n) = ( - 8 {m}^{3} )( \frac{25}{100} n) = - 2 {m}^{3} n$

3)

$(0.2p)( - 1.3 {q}^{2} ) = ( \frac{2}{10} p)( - \frac{13}{10} {q}^{2} ) = - \frac{13}{50} p {q}^{2}$

4)

$( - \frac{3}{7} {c}^{2} )( - \frac{5}{6} {b}^{3} ) = \frac{5}{14} {b}^{3} {c}^{2}$

233.

1)

$(3ab)( - 2 {a}^{2} b) = - 6 {a}^{1 + 2} {b}^{1 + 1} = - 6 {a}^{3} {b}^{2}$

2)

$( - 4 {x}^{2} y)( - 7x {y}^{2} ) = 28 {x}^{2 + 1} {y}^{1 + 2} = 28 {x}^{3} {y}^{3}$

3)

$(8a {b}^{2} )( \frac{1}{4} a {c}^{2} ) = 2 {a}^{1 + 1} {b}^{2} {c}^{2} = 2 {a}^{2} {b}^{2} {c}^{2}$

4)

$(6 {a}^{2} b)( \frac{1}{3} b {c}^{2} ) = 2 {a}^{2} {b}^{2} {c}^{2}$

234.

1)

$(3 {a}^{2} {b}^{5} c)(6 {a}^{ 3 }b {c}^{2} ) = 18 {a}^{2 + 3} {b}^{5 + 1} {c}^{1 + 2} = 18 {a}^{5} {b}^{6} {c}^{3}$

2)

$(7 {a}^{5} {b}^{2} c)( - 3a {b}^{4} c) = - 21 {a}^{5 + 1} {b}^{2 + 4} {c}^{1 + 1} = - 21 {a}^{6} {b}^{6} {c}^{2}$

3)

$( \frac{2}{3} {a}^{2} {b}^{3} x)( \frac{3}{4} {a}^{3} b {x}^{2} ) = \frac{1}{2} {a}^{2 + 3} {b}^{3 + 1} {x}^{1 + 2} =0.5 {a}^{5} {b}^{4} {x}^{3}$

4)

$( - \frac{3}{2} {a}^{3} x {y}^{3} )( \frac{3}{4} a {x}^{2} y) = - \frac{9}{8} {a}^{3 + 1} {x}^{1 + 2} {y}^{3 + 1} = - 1.125 {a}^{4} {x}^{3} {y}^{4}$
