(56/45)x^7

Explanation:

28x^4 20

---------- ÷ ----------- becomes

27 24x^3

28x^4 24x^3

---------- * ----------- if we invert the divisor fraction and then multiply.

27 20

We get: (28)(24)

-------------- x^7

(27)(20)

which reduces to (7)(24) x^7 (7)(8)x^7

--------------- = ------------- = (56/45)x^7

27(5) 9(5)

Answer 2

(56/45)x^7

Explanation:

28x^4 20

---------- ÷ ----------- becomes

27 24x^3

28x^4 24x^3

---------- * ----------- if we invert the divisor fraction and then multiply.

27 20

We get: (28)(24)

-------------- x^7

(27)(20)

which reduces to (7)(24) x^7 (7)(8)x^7

--------------- = ------------- = (56/45)x^7

27(5) 9(5)
