The error message "Invalid real operation" (Ошибка: Неверная вещественная операция) on line 4 most likely means that there is an issue with the way you are performing a mathematical operation with real numbers in your program.

In this case, it seems like the error might be related to the mathematical expression you are trying to evaluate. It's possible that there is a division by zero or some other invalid operation happening in the expression.

I suggest reviewing the mathematical expression and ensuring that there are no division by zero, square root of a negative number, or other invalid operations. Also, make sure that you are using the correct syntax for mathematical operations in Pascal.

If you're still having trouble, you may want to break down the expression into smaller parts and test them individually to identify where the issue is occurring.
