1. The problem is to express the phrase "in handwritten format" mathematically or clarify what is meant by "inb handwritten format." 2. Since "inb handwritten format" is unclear and not a standard math problem, we interpret it as a request for handwritten-style presentation or explanation. 3. As an AI text-based assistant, I provide explanations in clear, step-by-step markdown with LaTeX for math, which simulates a handwritten style in digital form. 4. If you want a specific math problem solved or written in a handwritten style, please provide the problem. 5. For now, this is a clarification and explanation rather than a math problem solution.
