この問題の(3)(4)はなぜ展開しなくていいのですか? それから展開せずに微分ってどうやるのか分かりやすく説明していただきたいです🙇🏻‍♀️‪‪´-

第2問 (配点 10) Your school is arranging a work experience programme for students in Years 10 and 11. As a member of the student council, you want to present 11/ some ideas to the school to make the programme a success. You have found a report written by the school council at a school in the UK which looks helpful. Work Experience Week Last month Work Experience Week was held at our school. A11 400 students in Years 10 and 11 were asked to participate. The school provided a list of companies that were willing to accept students for a week, and students were also given the chance to contact companies by themselves. Nevertheless, some of them failed to find a place to work. Students who were not successful in finding a company had to come to school for self- study, so we should find a better way to match up students and companies next year. According to the school, 6% of Year 10 students and 34% of Year 11 students didn't participate. Why was there such a difference? The comments below clearly show the reason for this. Feedback from participants Harry, I really enjoyed the work experience. I found my company from the school's list, so it was easy to set it up. Yu-ming: This was my second time, I'm happy I did it, but most kids in my year just wanted to study for their exams. Maybe it should just be for Year 10. Clara: I couldn't get my first choice, so the workplace was a bit too far. But I think the experience helped me to try harder. Mo: I arranged my own this year. The ones on the list are fine, but several students go to the same place. I wanted to be the only student, and this time I was. Ryan: I already know what I want to be (a physical therapist) and this 2, 3 LIKE 3 To
