Question

умоляю срочно помогите, 8 и 6 ​

Answer 1

Объяснение:

6)

$\frac{m {n}^{2} - 36m}{ {m}^{3} - 8 } \div \frac{2n + 12}{6m - 12} = \frac{m((n - 6)(n + 6))}{( {m - 2)}( {m}^{2} + 2m + 4) } \times \frac{6(m - 2)}{2(n + 6)} = \frac{3m(n - 6)}{( {m}^{2} + 2m + 4) }$

8)

$\frac{4 {x}^{2} - 100 }{6x} \div (2 {x}^{2} - 20x + 50) = \frac{4(x - 5)(x + 5)}{6x \times (2(x - 5)^{2}) } = \frac{4(x + 5)}{6x \times 2(x - 5)} = \frac{(x + 5)}{3x(x - 5)}$
