алгебра помогите пожалуйста!!​

Answer 1

Ответ:

5).

$\frac{40 {a}^{3}b }{7 {x}^{2} } \div \frac{25a {b}^{2} }{28x} = \frac{40 {a}^{3}b }{7 {x}^{2} } \times \frac{28x }{25a {b}^{2}} \\ = \frac{8 {a}^{2} }{x} \times \frac{4}{5b} = \frac{32 {a}^{2} }{5bx}$

6).

$\frac{48 {a}^{3} {b}^{3} {c}^{3} }{11x {y}^{2} } \div \frac{32a {b}^{2} {c}^{2} }{22 {x}^{2} y } = \frac{48 {a}^{3} {b}^{3} {c}^{3} }{11x {y}^{2} } \times \frac{22 {x}^{2}y }{32a {b}^{2} {c}^{2} } = \frac{3 {a}^{2} bc}{y} \times \frac{2x}{2} = \frac{3 {a}^{2} bcx}{y}$
