[計量] magoosh一題數學
Kim is taking a math class, and the teacher gives a multiple choice test consisting of 8 questions. If each question has 5 answer choices, and Kim answers every question, in how many different ways can she complete the test?
這題magoosh給的答案是五的八次方
如果我沒理解錯誤的話他是說每一天有五總方法選擇共八次
但是
如果一題多選題有五個選項
它的選法不是應該是2的五次方嗎？
還是我忽略了什麼
求解～
