2.{4}
3.{9/2}
Step-by-step explanation:
The equation can be solved as follows:
Then, the solutions of the equation are .
Now, if , we can solve the equation
as follows:
So, the unique solution of this last equation is
The last equation is , where
. To solve this equation we can proceed as follows:
But, x=11/4 is not a solution of this equation. So the unique solution is x=9/2.
