(-1/3a^3b ^2)^2(-2ab^2)^3/(1/9a^4b^4)^2
(-1/3a^3b ^2)^2(-2ab^2)^3/(1/9a^4b^4)^2
(-1/3a^3b ^2)^2(-2ab^2)^3/(1/9a^4b^4)^2
(-1/3a^3b ^2)^2(-2ab^2)^3/(1/9a^4b^4)^2
=(-8/9a^9b^10)/(1/81a^8b^8)
=-72ab^2
ab^3+b^2+b-a+1
(a-b)^3+2ab(a-b)
(a^2b-ab-a+1)/(ab^2+3ab-b-3)÷(a^2+a_2)/(b^2+b-6)
1/4a^2b^2{3ab(a+b)-5a(ab-b^2)}=?
1/a+1/b=3则a-ab+b/a+2ab+b值是?
如果a+b=3,ab=-1,那么(a+b)2-a-b+ab=?
ab/a+b=3 a-2ab+b/2a-3ab+2b?
a^2-3ab+b^2/ab=( )/ab-3
a^2-3ab+b^2/ab=( )/ab -3
-3/4ab+2/3a^2b+ab-a^2b-1/2ab-5/3a^2b
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
(-3ab)(a^2b-3ab^2+1)
当a-b等于-1,ab等于-2,(2a-3b-ab)-(a-2b+3ab)等于多少
当a-b=-1,ab=-2,(2a-3b-ab)-(a-2b+3ab)
A-B=-1,AB=-2,则(2A-3B-AB)-(A-2B+3AB)=?”
a-b=-2,ab=-1时,(3a-4b-ab)-(2a-3b+5ab)=?
已知a-b=-1,ab=-2,求代数式(3a-4b-ab)-(a-2b+3ab)
已知a-b=2,ab=-1 求(4a-5b-ab)-(2a-3b-5ab)
