The answer depend on what is being squared. Is it

or
?
Since I don't know which is right I cannot solve the problem. But I can tell you what to do. The arguments of all logarithms must be positive. So the solution will be whatever x-values will make the argument positive. So:
If the first equation is correct, then argument is x-5. The domain will be the solution to:
x - 5 > 0
If the second equation is correct, then the argument is .. The domain will be the solution to:

Note: Since squaring something never results in a negative, the only x's that are not in the domain are the x's that make zero. So an alternate way to find the domain is to solve:

and then the domain is all real numbers except the solution(s) to the equation above.

If you mean
then the domain is all real numbers since
will always result in a positive number.
