问题描述：
用整式除法计算,
1.(5x^2y^3)^2÷(25x^4y^5)
2.(x+y)^3÷(x+y)
3.(7a^5b^3c^5)÷(14a^2b^3c)
4.(8a^4b^3c)÷(2a^2b^3)·(-2/3a^3bc^2)
5.(3x^2y)·(-15xy^3)÷(-9x^4y^2)
用整式除法计算,
答
整式的除法,就是将除号变成分数线,然后,分子与分母进行约分即可.1、原式=25X^4y^6/25x^4y^5=y2、原式=.(x+y)^3/(x+y) =.(x+y)^23、原式=(7a^5b^3c^5)/(14a^2b^3c) =a^3c^4/24、原式=4a^2c*(-2/3a^3bc^2)= -8/3a^5bc^...
