Log2 x + log3 x< log3 6

Question

Log2 x + log3 x< log3 6

Answer 1

ОДЗ:x>0
log 2 (x)=(log 3 (x))/(log 3 (2)
(log 3 (x))/(log 3 (2)+log 3 (x) < log 3 (6) 
log 3 (x) (1/log 3 (2) +1)< log 3 (6) <br>log 3 (x) (log 3 (2) +1)/(log 3 (2)< log 3 (6)<br>log 3 (x) (log 3 (6))/log 3 (2)0
(log 3 (x))/(log 3 (2)) <1 |*  log 3 (2)>0
log 3 (x)x<2<br>ОДЗ: x>0

Ответ: х∈(0; 2)
