Final answer:
When adding parentheses to an expression, we follow the order of precedence rules. In the given expression 01 | 0(01)*, the result is true.
Step-by-step explanation:
When adding parentheses to an expression, we follow the order of precedence rules which dictate the order in which operations should be performed. In the given expression 01 | 0(01)*, the operation inside the parentheses should be evaluated first.
The expression (01)* means that the sequence "01" can be repeated zero or more times. So, for each occurrence of "01" in the expression, we substitute it with "01" itself. Thus, the expression becomes 01 | 001.
Next, we perform the OR operation represented by the pipe symbol (|). This means that if any of the operands is true, the result is true. In this case, 01 is true and 001 is also true. So, the final result is true.
