4.(ab^2)^3-(ab)^3×b^3要有过程
1.-(2ab)^3+3ab×a^2b^2
=-8a^3b^3+3a^3b^3
=-5a^3b^3
2.(x^2y^3)^4+(-x)^8(y^6)^2
=x^8y^12+x^8y^12
=2x^8y^12
3.(-3a^2)^3×a^3+(-4a)^2a^7-(5a^3)^3
=-27a^9+16a^9-125a^9
=-136a^9
4.(ab^2)^3-(ab)^3×b^3
=a^3b^6-a^3b^6
=0
=-8a^3b^3+3a^3b^3
=-5a^3b^3
2.(x^2y^3)^4+(-x)^8(y^6)^2
=x^8y^12+x^8y^12
=2x^8y^12
3.(-3a^2)^3×a^3+(-4a)^2a^7-(5a^3)^3
=-27a^9+16a^9-125a^9
=-136a^9
4.(ab^2)^3-(ab)^3×b^3
=a^3b^6-a^3b^6

几道因式分解..4ab(a+b)^2-6a^2b(a+b)(x+y)^2(x-y)+(x+y)(x-y)^22a(a-3
1.-(2ab)^3+3ab×a^2b^2 2.(x^2y^3)^4+(-x)^8(y^6)^2 3.(-3a^2)^3
x²（x+y)(y-x)-xy(x+y)(x-y) 已知a+b=4,ab=-2,求多项式3a²b+3
因式分解-6a^3+4ab^3-2a^2b,3a^2(x-y)+27(y-x)
分解公因式的题 x（a-x）(a-y)-y(x-a)(y-a)-ab(a-b)^2+a(b-a)^2a^3b-ab2ab
计算：(2a-5b)(2a^2-3ab+b^2) （3x+2y)(2x+3y)-(x-3y)(3x+4y)
(3a+b)(3a-b) (-1/2a-b) (3y+2x)^2 (3ab+2b)^2 -8a^4b^/6ab^2 (3
计算:(-2a^2b)(2/3ab^3)(-6b^2c^3) (x+y)(x-y)-(x-2y)(x+2y) (3x-2
因式分解 1)9x^4-25y^6 2)4x^2+(x+y)^2+4x(x+y) 3)(a+2b)^2-4ab-13b^

①[(x+y)^2-(x+y)(x-y)]/2y②（-1/3a^3b^2)^2(-2ab^2)^3/(1/9a^4b^4
有理数ab定义:a*b=3a+2b.则[（x+y)*(x-y)]*3x.怎么化简?
