以下是引用amacd在2005-10-17 13:53:00的发言:one more question: DS: if the integer a and n are greater than 1, and the product of the first 8 positive interger is a multiple of a^n, what is the value of a? a) a^n = 64 b) n = 6, answer is b can someone help to explain the hightlighted part>? thanks alot !!!  如果条件改为:if the integer a and n are greater than 3 ,后面的不变, 是不是就可以表示为 =9*8*7**6*5*4 呢?因为对and the product of the first 8 positive interger 这句话不是很理解 谢谢 |
