化简(3/4ab+3ab-2/3b)(1/2ab)化简(3/4ab+3ab-2/3b)(1/2ab)化简(3/4ab+3ab-2/3b)(1/2ab)(3/4ab+3ab-2/3b)(1/2ab)=3
化简(3/4ab+3ab-2/3b)(1/2ab)
化简(3/4ab+3ab-2/3b)(1/2ab)
化简(3/4ab+3ab-2/3b)(1/2ab)
(3/4ab+3ab-2/3b)(1/2ab)
=3/8a²b²+3/2a²b²-1/3ab²
=15/8a²b²-1/3ab²
化简(3/4ab+3ab-2/3b)(1/2ab)
化简ab-2{ab-[3a²b-(4ab²+2/1ab)-3a²b]}-3ab²
a^2b-ab+2ab^2-5a^b-4ab+3ab^2化简快
3a²b-[2ab²-6(ab-1/2a²b)+4ab]-2ab
ab-[3ab-(4ab^2+1)]-4ab^2化简.(要有过程)
ab-[3ab-(4ab^2+1)]-4ab^2化简.
化简:a-(3ab+b)+(3a-4b-ab)
合并同类项5a²b-3ab-4ab²+7ab-2ab²
(-1/2ab)(2/3ab^2-2ab+4/3b)
(-1/2ab)(2/3ab^2+2ab-4/3b)
化简 3a²-[2ab-2(ab-3/2a²b)+ab]+4ab²
5ab-2[3ab-(4ab²+2分之1ab)]-5ab²
5ab平方-{2a平方b-[3ab平方-(4ab平方-2ab平方)]},其中ab满足|a-2|+(b+1)平方=0
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-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)
