1. Let's clarify what DNE (Does Not Exist) means in mathematics. It indicates that a limit, value, or solution is not defined or does not have a finite or meaningful value. 2. To determine if an answer is indeed DNE, we generally check if a function approaches infinity, oscillates without settling, or is undefined due to division by zero or other domain restrictions. 3. Without a specific problem, I cannot explicitly verify if the answer is DNE. Please provide the problem or expression related to this answer, and I will help you confirm or find the correct solution. 4. If you need help with limits, solving equations, or any other topic where DNE might arise, please share the full context for accurate assistance.
