(25a^2b^2-10ab)÷5ab+32ab^3÷（-2b)^2怎么做

(25a^2b^2-10ab)÷5ab+32ab^3÷（-2b)^2怎么做 -5a(a^2b-ab^2)÷ab 10a^2b+5ab^2-15ab 因式分解 a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快 已知a+b=3ab,求代数式(5a+ab+5b)÷(a-2ab+b)的值. a^2b^2-10ab+25 a+b/2ab 2AB/A+B a+b/2ab -ab(a^2b^5-ab^3-b) 若a-b=10,ab=6,求：ab-2ab+ab的值 合并同类项5a²b-3ab-4ab²+7ab-2ab² 计算：a2-2ab/-ab+b2÷(a2/a-b÷2ab/2b-a) 5ab^2-{2a^b-[3ab^2-(4ab^2-2a^2b)]} 已知a+b=10,ab=2,则3a-(5ab-3b)=! (-a^2b^2)÷(-ab^2)×(-3ab^3) (-a^2b^2)÷(-ab^2)*(-3ab^3) -5a^2b^3+20ab^2-5ab
