[(3ab-2)(3ab+2)+(2ab+2)²]/5ab=v[(3ab-2)(3ab+2)+(2ab+2)²]/5ab=v[(3ab-2)(3ab+2)+(2ab+2)²
[(3ab-2)(3ab+2)+(2ab+2)²]/5ab= v
[(3ab-2)(3ab+2)+(2ab+2)²]/5ab= v
[(3ab-2)(3ab+2)+(2ab+2)²]/5ab= v
(3ab-2)(3ab+2)+(2ab+2)2]/5ab
=(9a^2b^2-4+4a^2b^2+8ab+4)/5ab
=(13a^2b^2+8ab)/5ab
=13/5ab+8/5
[(3ab-2)(3ab+2)+(2ab+2)²]/5ab
=（9a^2b^2-4+4a^2b^2+8ab+4)/5ab
=(13a^2b^2+8ab)/5ab
=13ab/5+8/5
3ab(ab的平方+2ab)
5ab-2[3ab-(4ab²+2分之1ab)]-5ab²
(2/3ab^2-2ab)*1/2ab
(2/3ab^2-2ab)×1/2ab
计算:(3ab^2)^2 + (-4ab^3) * (-ab)
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
3(a2-2ab)-(-ab+b2)+(2ab+b2)
计算(-2ab)×3ab=
2ab+3ab等于多少?
[(3ab-2)(3ab+2)+(2ab+2)²]/5ab=
[(3ab-2)(3ab+2)+(2ab+2)²]/5ab= v
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
化简：(-3ab)(-5ab)+2/3ab的二次方(7/3ab-2a)
已知a＋b=3,ab=2 求 ab+2ab+ab 的值
计算：2ab[(2ab)²-3b(ab+a²b)-ab²]
ab-[3ab-(4ab^2+1)]-4ab^2化简.（要有过程）
ab-[3ab-(4ab^2+1)]-4ab^2化简.
