几个多项式相乘请问:(a-b)²(b-a)³(a-b)³=(a-b)的2n次方(b-a)³=(-x+y)(x-y)²(y-x)³=还有:(-2x²)(-3x²y³z)=(-ab³c²)²×(-a²b)³=

几个多项式相乘
请问:(a-b)²(b-a)³(a-b)³=
(a-b)的2n次方(b-a)³=
(-x+y)(x-y)²(y-x)³=
还有:(-2x²)(-3x²y³z)=
(-ab³c²)²×(-a²b)³=

(a-b)²(b-a)³(a-b)³=-(a-b)^8
(a-b)的2n次方(b-a)³=(a-b)^(2n-3)
(-x+y)(x-y)²(y-x)³=(y-x)^6
(-2x²)(-3x²y³z)=6x^4y^3z
(-ab³c²)²×(-a²b)³=-a^8b^9c^4
