^3ab^2-5ab^3-3ab^2+5b^3a-8a^3b^2+8a^2b^3化简
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)

5ab-2[3ab-(4ab²+2分之1ab)]-5ab² 3ab(ab的平方+2ab) [(3ab-2)(3ab+2)+(2ab+2)²]/5ab= [(3ab-2)(3ab+2)+(2ab+2)²]/5ab= v 化简：(-3ab)(-5ab)+2/3ab的二次方(7/3ab-2a) a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快 合并同类项5a²b-3ab-4ab²+7ab-2ab² 已知（a-2）+（b+1）=0,求多项式3ab+ab-3ab+5ab+ab+2分之1ab 因式分解：(ab^2)^2×(-a^3b)^3×(-5ab) -3ab-4a^2+3a^2+5ab -5a^2b^3+20ab^2-5ab 2ab(5ab^2+3a^2b)急要 化简 3a2-ab/3a2+5ab-2b2 (5ab)的2次方+(3ab)的2次方 计算：5ab-a²-2(ab-3a)² 2ab*(5ab²+3a²b) (-3)*2ab+5ab*6怎么化简 化简.(-3) x 2ab + 5ab x 6
