3ab^2-5ab^3-3ab^2+5b^3a-8a^3b^2+8a^2b^3怎么算
3ab^2-5ab^3-3ab^2+5b^3a-8a^3b^2+8a^2b^3?
=3ab^2-3ab^2-5ab^3+5ab^3
=0+0+8a^2b^3-8a^3b^2
=8a²b²(b-a)

a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快合并同类项5a²b-3ab-4ab²+7ab-2ab² -ab(a^2b^5-ab^3-b) 5ab-2[3ab-(4ab²+2分之1ab)]-5ab² 因式分解：(ab^2)^2×(-a^3b)^3×(-5ab) -5a^2b^3+20ab^2-5ab 2ab(5ab^2+3a^2b)急要 2ab*(5ab²+3a²b) 5ab^2-{2a^b-[3ab^2-(4ab^2-2a^2b)]} ab^2=一3,则-ab(a^2乘b^5-ab^3-b)=? 已知ab^2=-3,则-ab(a^2b^5-ab^3-b)=? ab^2=3 求-ab(a^2b^5-ab^3-b)值已知ab^2=-2,求-ab(a^2b^5-ab^3-b)的值化简求值-ab*(a^2b^5-ab^3-b),其中ab^2=-2 -ab(a^2b^5-ab^3-b),其中ab^2=-2 已知ab^2=6,求ab(a^2b^5-ab^3-b)的值已知ab^2=-6,求-ab(a^2b^5-ab^3-b)的值已知ab^2=6,求ab(a^2b^5-ab^3-b)的值
