不等式|2x-1-log3(x-1)|<|2x-1|+|log3(x-1)|的解集是________.
网友回答
(2,+∞)
解析分析:由|2x-1-log3(x-1)|<|2x-1|+|log3(x-1)|?2x-1与log3(x-1)同号且为正,从而可求得其解集.
解答:∵|2x-1-log3(x-1)|<|2x-1|+|log3(x-1)|?|(2x-1)-log3(x-1)|2<(2x-1)2+log32(x-1)+2(2x-1)?log3(x-1)?4(2x-1)?log3(x-1)>0,∴,解得x>2;或,x∈?,∴不等式|2x-1-log3(x-1)|<|2x-1|+|log3(x-1)|的解集是(2,+∞).故
