解不等式log1-k(2k-1)<11-k为底解不等式log1-k(2k-1)<11-k为底解不等式log1-k(2k-1)<11-k为底log(1-k)(2k-1)答:log(1-k)(2k-1)1

解不等式log1-k (2k-1)<1 1-k为底
解不等式log1-k (2k-1)<1 1-k为底

解不等式log1-k (2k-1)<1 1-k为底
log(1-k)(2k-1)

答:
log(1-k) (2k-1)<1
1)当0<1-k<1即02k-1>1-k>0
3k>2
k>2/3
所以:2/32)当1-k>1即k<0时:
0<2k-1<1-k
所以:
k>1/2并且k<2/3
无解
综上所述,2/3
