✔ 最佳答案
5a3b-3b3a+2ba3-b3a=5a3b+2a3b-3b3a-b3a
=7a3b-4b3a

5a3b-3b3a 2ba3-b3a=5a3b 2a3b-3b3a-b3a=7a3b-4b3a

5a^3b - 3b^3a + 2ba^3 - b^3a
= 5a^3b + 2a^3b - 3b^3a - b^3a
=7a^3b - 4ab^3
=ab (7a^2 - 4b^2)
= 5a^3b + 2a^3b - 3b^3a - b^3a
=7a^3b - 4ab^3
=ab (7a^2 - 4b^2)

5a^3b - 3b^3a + 2ba^3 - b^3a
= 5a^3b + 2a^3b - 3b^3a - b^3a
=7a^3b - 4ab^3
=ab (7a^2 - 4b^2)
= 5a^3b + 2a^3b - 3b^3a - b^3a
=7a^3b - 4ab^3
=ab (7a^2 - 4b^2)
