(-2)³·(-2)²=
(2x²)²+(-3x)³·(-2x)=?
1/2 x²y·( )=2x³y-x²y²
(3x²y)³×(-4x)= (-2a)³·(-3a)²=
计算:(-x)²x³·(-2y)³-(-2xy)²·(-3x)³y.
(-x)²·x³·(-2y)³+(2xy)²·(-x)³·y
1.(-m²)³·(-2m³)²
(-2)³·(-2)²·(-2)⁴
2/5x²y·(-0.5xy)²-(-2x)³·xy³
(1)(-2x²y³)²·(xy)³ (2)(2a+3b)(2a-b)
1.(-2a)³·b²÷(8a³b²)
计算:2(x²y³)³-(x³y²)²·y的5次方-(x
计算:(2x²)²+(-3x)³·(-2x) 第二
