(3b)^2= 2.—(ab)^2 3.(-4a^2)^3 4.(y^2z^3)^3 5.(xy^3n)^2+(xy^6)^n 6.(-3x^3)^2-[(2x)^2]^3
(3b)^2= 2.—(ab)^2 3.(-4a^2)^3 4.(y^2z^3)^3 5.(xy^3n)^2+(xy^6)^n 6.(-3x^3)^2-[(2x)^2]^3

(3b)^2 = 9b^2
-(ab)^2 = -a^2b^2
(-4a^2)^3 = -64a^6
(y^2z^3)^3 = y^6z^9
(xy^(3n))^2+(xy^6)^n = x^2y^(6n) + x^ny^(6n)
(-3x^3)^2-[(2x)^2]^3 = 9x^6 - 8x^6 = x^6
ab(a^2b^5-ab^3+b),其中ab^2=-3.
3ab+b^2+( )=4ab-b^2.(括号里填一个数)
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
(a+ab)-[(ab-2b)-a]-(-9ab),其中a+b=-7,ab=3.
a+b=5 ab=-3 (2a-3b-2ab)-(a-4b-ab)
已知ab/(a+b)=3,求(3a+ab+3b)/(2a-ab+2b)的值
2ab+b^2+什么 =3ab-b^2
a-b=3ab,则代数式2a-2b-ab/a-b+2ab的值是()
a-b=3ab,则代数式2a-2b-ab/a-b+2ab的值是()
2ab+b²+( )=3ab-b²
2ab+b²+ =3ab-b²
a-b=5 ab=--1求(2a+3b-2ab)-(a+4b+ab)-(3ab-2a+2b)的值
a²-ab=3,3ab-b-b²=4 求2(a²+ab-b²)+a²-2ab+b²
已知a+b=-2.ab=3.求2〔ab+(-3a)〕-3(2b-ab)的值 已知a+b=-2.ab=3.求2〔ab+(-3a)〕-3(2b-ab)的值
已知A-B-3AB=3.则分式A-B-6AB/2A-2B+3AB的值()
ab/a+b=3 a-2ab+b/2a-3ab+2b?
已知a+b=1/2,ab=1/3.求多项式(-2ab+2a+3b)-(3ab+2ab-2a)-(a-2b+ab)的值
