The image contains a mathematical problem in Bulgarian, focusing on simplifying or solving the expression $\frac{\sqrt{x-3}}{x-5}$.

Would you like me to:

1. Simplify or transform this expression?
2. Evaluate it for specific values of $x$?
3. Solve for conditions such as when it equals a specific value?
4. Discuss its domain and restrictions?
5. Provide a detailed explanation of the solution process?

Let me know if you’d like a breakdown or specific focus! Here's a tip: Always check the domain of the function to avoid undefined operations like division by zero or taking the square root of a negative number.
