РЕШИТЕ НОМЕР 3 ПЛИИЗ

Answer 1

Объяснение:

$\frac{36 {m}^{7} {n}^{5} {k}^{3} }{81 {m}^{5} n {k}^{4} } = \frac{4 {m}^{2} {n}^{4} }{9k}$

$\frac{ - 9 {a}^{2} + 24ab - 16 {b}^{2} }{6 {a}^{2} - 8ab} = \frac{ - {(3a - 4b)}^{2} }{2a(3a - 4b)} = - \frac{3a - 4b}{2a}$

$\frac{xy - xk + ay - ak}{mx + ma + nx + na} = \frac{x(y - k) + a(y - k)}{m(x + a) + n(x + a)} = \frac{(x + a)(y - k)}{(m + n)(x + a)} = \frac{y - k}{m + n}$
