Помогите с алгеброй срочно!!!

Answer 1

Ответ:

$- \frac{14 {c}^{12} }{ {a}^{6} {b}^{11} } \times \frac{ {a}^{5} {b}^{9} }{52 {c}^{7} } = - \frac{ 7{c}^{5} }{26a {b}^{2} }$

$\frac{7a - 7b}{2 {c}^{4} } \times \frac{6c}{ {a}^{2} - {b}^{2} } = \frac{7(a - b)}{2 {c}^{4} } \times \frac{6c}{(a - b)(a + b)} = \frac{21}{ {c}^{3} (a + b)}$

$\frac{84 {z}^{9} {y}^{6} }{ {x}^{11} } \times \frac{1}{48x {y}^{14} {z}^{7} } = \frac{7 {z}^{2} }{4 {x}^{12} {y}^{8} }$
