To solve the inequality
, we can use the properties of logarithms.First, let's simplify the left side of the inequality using the quotient rule of logarithms:
So the inequality becomes:
Since the base of the logarithms is
, which is less than 1, the inequality sign will be reversed when taking the logarithm:
Now, let's solve this inequality:
We can solve this quadratic inequality by factoring:
The critical points are
and
. We can test the intervals to find the solution set:For
, the inequality is true.For
, the inequality is false.For
, the inequality is true.Therefore, the solution set for the inequality
is
.
