计算:2(x²y³)³-(x³y²)²·y的5次方-(x³y的4次方)²·y.计算:2(x²y³)&

计算:2(x²y³)³-(x³y²)²·y的5次方-(x³y的4次方)²·y.
计算:2(x²y³)³-(x³y²)²·y的5次方-(x³y的4次方)²·y.

计算:2(x²y³)³-(x³y²)²·y的5次方-(x³y的4次方)²·y.
2(x²y³)³-(x³y²)²·y的5次方-(x³y的4次方)²·y
=2x^6y^9-x^6y^4*y^5-x^6y^8·y
=2x^6y^9-x^6y^9-x^6y^9
=0

原式=2x的六次方y的九次方-x的6次方y的九次方-x的六次方y的九次方
=0
