3a^2b-[2abc-(2abc-ab^2c)+3a^2b]a=-4b=1/2c=33a^2b-[2abc-(2abc-ab^2c)+3a^2b]a=-4b=1/2c=33a^2b-[2abc-(2
3a^2b-[2abc-(2abc-ab^2c)+3a^2b] a=-4 b=1/2 c=3
3a^2b-[2abc-(2abc-ab^2c)+3a^2b] a=-4 b=1/2 c=3
3a^2b-[2abc-(2abc-ab^2c)+3a^2b] a=-4 b=1/2 c=3
3a^2b-[2abc-(2abc-ab^2c)+3a^2b]
=3a²b-(2abc-2abc+ab²c+3a²b)
=3a²b-ab²c-3a²b
=-ab²c
不懂的欢迎追问..
5abc-2a^2b-[3abc-3(4ab^2+a^2b)]
化简5abc-|2a^2-[3abc-(4ab^2-a^2b)]|
计算abc-[2ab-(3abc-ab)+4abc]=?
abc-[2ab-(3abc-bc)+4abc]其中a=2b=-1/2c=-1
计算:abc-[2ab-(3abc-bc)+4abc其a=2,b=0.5,c=1
24ab^2c^2(a+b-c)-32abc(a-c-b)^2+8abc^3(c-a-b)
因式分解abc+a^2b-ab^2-a+b-c
abc-[2ab-(3ab-bc)+4abc]a=2.b=-2分之1.c=-1
化简求值5abc-(2a^2b-[3abc-(4ab^2-a^2b])
正数abc 满足3+a平方+b平方+c平方小于等于ab+3b+2c-1 求abc
5abc-{2的平方b-[3abc-(4ab平方-a的平方b)]}写出过程
因式分解:-a^2b^3+2abc^2-3abc
a^2b-ab^2+a^c-ac^2-3abc+b^2c+bc^2
证明a^2+b^2-2ab ≥a^3+b^3+c^3-3abc
-{2a²b-[3abc-(4ab²-a²b)]}
abc为正数,a+b+c=1求ab^2c+abc^2最大值
已知实数abc满足a=6-b,c^2=ab-9,求abc
abc-[2ab-(3ab-bc)+4abc]怎吗写?
