a^2b-ab-a+1/ab^2+3ab-b-3除a^2+a-2/b^2+b-6fvdsf
a^2b-ab-a+1/ab^2+3ab-b-3除a^2+a-2/b^2+b-6 =(ab-1)(a-1)/(ab-1)(b+3)除a^2+a-2/b^2+b-6 =(a-1)/(b+3)*(b^2+b-6)/(a^2+a-2) =(a-1)/(b+3)*(b+3)(b-2)/(a+2)(a-1) =(b-2)/(a+2)
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
(-3ab)(a^2b-3ab^2+1)
a+b/2ab
2AB/A+B
a+b/2ab
(a+b-2ab)(a+b-2)+(1-ab)^2
3a²b-[2ab²-6(ab-1/2a²b)+4ab]-2ab
ab^3+b^2+b-a+1
求3ab(a^b+ab^2-ab)-ab^2(2a^2+3ab-2a)的值
3ab(a²b-ab²-ab)-ab²(2a²-3ab+2a)
3ab(a²b-ab²-ab)-ab²(2a²-3ab+2a)
3ab·(a²b-ab²+ab)-ab²(2a²-3ab+2a)
3ab(a²b-ab²-ab)-ab²(2a²-3ab+2a)
计算:2ab[(2ab)²-3b(ab+a²b)-ab²]
3ab{(-2ab)平方-3b(ab-a平方b)+ab平方}算出来多少Rt
ab/a+b=3 a-2ab+b/2a-3ab+2b?
