化简:[(-2xy^2)^3*(-3x^2y^3)+(-2xy^2)^2*(3x^2y^3)^2*xy^2]/(x^5y^12)

问题描述:

化简:[(-2xy^2)^3*(-3x^2y^3)+(-2xy^2)^2*(3x^2y^3)^2*xy^2]/(x^5y^12)
谢谢

原式=[(-2xy²)³×(-3x²y³)+(-2xy²)²×(3x²y³)²×xy²]/(x^5y^12)=[(-8x³y^6)×(-3x²y³)+(4x²y^4)×(9x^4y^6)×xy²]/(x^5y^12)=(24x^5y^...谢谢,再问一道行吗?2^2010*(-1/2)^2008你好:就再解一道2^2010×(-1/2)^2008=2²×2^2008×(-1/2)^2008=4×[2×(-1/2)]^2008=4×(-1)^2008=4×1=4
