已知实数a,b满足ab>0,则带数式a²+2b²/2ab 有没有最大值或最小值

已知实数a,b满足ab 已知实数a,b满足ab 已知实数a,b满足ab>0,则带数式a²+2b²/2ab 有没有最大值或最小值 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 ,|ab|+ab=0 化简 ：|a|+|-2b|-|3b-2a| 已知实数a.b满足0 已知存在实数a满足ab^2>a>ab,则实数b的范围rt 已知实数a,b满足a+b>0,b 已知实数a,b满足ab-6=0,a+b=7,那么a-b的值是 已知实数a,b满足√a-1+√b+2=0,求a ,b,√-ab.如题 已知实数a,b满足ab=1,a/1+a+b/1+b求值, 已知实数ab满足a方+ab-b的方=0,则b分之a=? 已知实数a,b,c,满足a 已知实数a,b满足a+b=-4,ab=3,a 已知实数a满足0 已知实数a满足0 已知实数a,b满足条件a*a+b*b+a*ab*b=4ab-1 已知正实数ab,满足ab=a+b,则a分之b+b分之a-ab=多少
