Answer 1

Ответ:

$5) \frac{ {c}^{2} }{ {a}^{4} } \times \frac{ {a}^{3}b }{c} = \frac{ {c}^{2} \times {a}^{3}b }{ {a}^{4} \times c} = \frac{c \times b}{a} = \frac{cb}{a}$

$8) 12 {x}^{2} \times \frac{ {y}^{2} }{6 {z}^{2} } = \frac{12 {x}^{2} \times {y}^{2} }{6 {z}^{2} } = \frac{2 {x}^{2} \times {y}^{2} }{ {z}^{2} }$
