(1)(-2x²y)³+8(x²)²*(-x)²*(-y)³(2)(-x²)³*x³-(2x³)³+5x^4*x^5
(1)(-2x²y)³+8(x²)²*(-x)²*(-y)³
=-8x的6次方y³-8x的6次方y³
=-16x的6次方y³
(2)(-x²)³*x³-(2x³)³+5x^4*x^5
=-x的9次方-8x的9次方+5x的9次方
=-4x的9次方

您好:
(1)(-2x²y)³+8(x²)²*(-x)²*(-y)³
=8x的6次方y的3次方-8x的6次方y的3次方
=0
(2)(-x²)³*x³-(2x³)³+5x^4*x^5
=-x的9次方-8x的9次方+5x的9次方
=-4x的9次...
