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?
这题magoosh给的答案是五的八次方
如果我没理解错误的话他是说每一天有五总方法选择共八次
但是
如果一题多选题有五个选项
它的选法不是应该是2的五次方吗?
还是我忽略了什么
求解~
