1. You asked to have the solution formatted for a Word document. 2. Since I provide text-based solutions with LaTeX for math, you can copy the solution directly as text. 3. To put it in a Word document, simply open Word, paste the content, and you can adjust fonts and styles as needed. 4. If Word supports Equation Editor, you can insert the LaTeX math into Word's equation editor for proper formatting. If you want me to resend the solution text again for easy copying, please specify which solution you want.
