|8a+3|+|4b|+|5c+2|=0 求abc+2004

|8a+3|+|4b|+|5c+2|=0 求abc+2004
|8a+3|+|4b|+|5c+2|=0 求abc+2004

|8a+3|+|4b|+|5c+2|=0 求abc+2004
绝对值之和等于0
则：8a+3=0
4b=0
5c+2=0
得到b=0
所以abc+2004=0+2004=2004

|8a+3|+|4b|+|5c+2|=0
8a+3=0,4b=0,5c+2=0
a=-3/8,b=0,c=-2/5
abc+2004=0+2004=2004

8a+3=0,a=-3/8
4b=0,b=0
5c+2=0,c=-2/5
abc+2004=0+2004=2004

|X|>=0
|8a+3|+|4b|+|5c+2|=0
8a+3=0,a=-3/8
4b=0,b=0
5c+2=0,c=-2/5
abc+2004
=(-3/8)(0)(-2/5)+2004
=2004
