38.3.Приведите к дроби со знаменателем 4a⁵c² дробь:​

Answer 1

1)

$\frac{4a}{ {a}^{3}c } = \frac{4a \times 4 {a}^{2}c }{4 {a}^{5} {c}^{2} } = \frac{16 {a}^{3}c }{4 {a}^{5} {c}^{2} }$

2)

$\frac{5a {c}^{3} }{ {a}^{2} c} = \frac{5a {c}^{3} \times 4 {a}^{3}c }{?} = \frac{20 {a}^{4} {c}^{4} }{4 {a}^{5} {c}^{2} }$

3)

$\frac{4a}{2a {c}^{2} } = \frac{4a \times 2 {a}^{4} }{4 {a}^{5} {c}^{2} } = \frac{8 {a}^{5} }{4 {a}^{5} {c}^{2} }$

4)

$\frac{a {c}^{4} }{0.5ac} = \frac{a {c}^{4} \times 8 {a}^{4} c}{4 {a}^{5} {c}^{2} } = \frac{8 {a}^{5} {c}^{5} }{4 {a}^{5} {c}^{2} }$

5)

$\frac{5.5ac}{ {a}^{2} c} = \frac{5.5ac \times 4 {a}^{3} c}{4 {a}^{5} {c}^{2} } = \frac{22 {a}^{4} {c}^{2} }{4 {a}^{5} {c}^{2} }$

6)

$\frac{ - ax}{ {a}^{3}c } = \frac{ - ax \times 4{a}^{2}c }{4 {a}^{5} {c}^{2} } = \frac{ - 4 {a}^{3} cx}{4 {a}^{5} {c}^{2} }$
