解答
|3a-2b-2|-|4-3a+2b|
=(2b+2-3a)-(4-3a+2b)
=2b-3a+2-4+3a-2b=-2
推荐
- 当a大于0,b小于0,化简(3-2b的绝对值)+(b-3a的绝对值)-3(b-a的绝对值)=?
- 若a大于0,b小于0时,化简绝对值6-5b+绝对值8b-1-绝对值3a-2b的结果是
- 已知有理数a,b在数轴上,如图所示化简:a-b的绝对值-a+b的绝对值+2b-3a的绝对值 (b<-1,a<1)
- 化简3a^2-[2ab^2-2(ab-二分之三a^2b)]-2ab,其中a,b满足a+b的绝对值+(a-2)^2=0
- 已知a是负数,b是正数,且a的绝对值大于b的绝对值,化简|a+b|-2|a-b|-|2b-3a
- Which is your middle school=which one is your middle school.
- 仔细说明白!
- 已知代数式x+y=5,xy=10,求x²+y²的值
