1.若实数a、b满足|3a-1|+|b-2|=0,求a+b的值.2.计算（+1）+（-2）+（+3）+（-4）+…+（+2003）+（-2004）今晚要用,请写详细点,

实数a.b满足-1 若实数a,b满足a+b 1.若实数a,b满足0 若实数a,b满足|3a-1|+|b-2|=0,求(a+b)×|-b|/7的值 若实数a,b满足0 若实数a,b满足0 已知实数a,b满足：1 已知实数a,b满足：1 已知实数a,b满足1 实数a,b满足0 实数a,b满足0 若实数ab满足a³+b³+3ab=1,则a+b= 实数a,b满足a*a*a+b*b*b+3ab=1,则a+b= , 实数A,B满足A*A*A+B*B*B+3ab=1,求A+B的值 若实数a,b满足a+b=2,求3^a+3^b的最小值 若实数a,b满足a+b=2则3^a+3^b最小值是 若实数A,B满足|3A+1|+(B+1)²=0,则A的B次方=? 若实数a、b满足：|3a+1|+b的平方=0,则a的b次方=
