Question

Log0.7(x-4)>log0.714

Answer 1

$log_{0,7}(x-4)<log_{0,7}14< var=$

 

$<var>y=log_{0,7}x$     ОДЗ: x>0

 

$log_{0,7}(x-4)<log_{0,7}14< var=$     ОДЗ: x>0

 

$<var>y=log_{0,7}x" />-убывающая, поэтому  x-4<14</var></p> <p>                                                                                x<18</p> <p>[tex]xin(0;18)$
