已知实数a.b满足a ＞＝0,b ＞＝0,a -b +1＞＝0,则z =a +b.的取值范围是多少

已知实数a.b满足0 已知实数a,b满足a+b>0,b 实数a,b满足0 实数a,b满足0 已知实数a、b满足实数(a+b)^2+a+b-2=0,求a+b的值 已知实数a,b,c,满足a 已知实数a.b满足a ＞＝0,b ＞＝0,a -b +1＞＝0,则z =a +b.的取值范围是多少 已知实数a,b,c满足a>0,a-b+c 实数a,b满足（a+b）²+a+b-2＝0,则（a+b）²的值 已知实数a,b满足|a|=b,|ab|+ab=0,化简|a|+|-2b|-|3b-2a| 已知实数a,b满足(a+b)的平方+a+b-2=0,求a+b的值 已知实数a b.满足(a+b)平方+a+b-2=0求a+b的值 已知实数a、b满足(a+b)方+a+b-2=0,求a+b的值 已知实数a,b 满足|a|=b ,|ab|+ab=0 化简 ：|a|+|-2b|-|3b-2a| 1.若实数a,b满足0 若实数a,b满足0 若实数a,b满足0 已知实数a,b满足ab
