(-x)^2×x^3×(-2y)^3+(-2xy)^2×(-x)^3×y
(-x)^2×x^3×(-2y)^3+(-2xy)^2×(-x)^3×y
(-x)^2×x^3×(-2y)^3+(-2xy)^2×(-x)^3×y
(-x)^2×x^3×(-2y)^3+(-2xy)^2×(-x)^3×y
=-x^2×x^3×8y^3-4x^2y^2×x^3×y
=-8x^5y^3-4x^5y^3
=-12x^5y^3
=-12x^5y^3
原式=x^2·x^3×8y^3-4x^2y^2×x^3×y
=-8x^5y^3-4x^5y^3
=-12x^5y^3
-12x^5y^3
题目完整吗？照以上提供的式子可以算到以下结果：
（-x)^2×x^3×(-2y)^3+(-2xy)^2×(-x)^3×y=（x²）×（x³）×（-8y³）+（4x²y²）×（-x³）×y
=-8x...
