I put domain x>0, it was correct, but for the answer I got x<9, and it says incorrect in my system, so what is the answer?

log(3)(-n) do not exist therefore x>0 , so I agree the firs part of your answer.
log(3)(x)=2 when x=3^2=9
Therefore every x less than is inthe domain.
The answer is then 0<x<9
log(3)(x)=2 when x=3^2=9
Therefore every x less than is inthe domain.
The answer is then 0<x<9

( 0 , 9 ) or 0 < x < 9
