Baby,n=0时,1除以3怎么余1啊?!!它有余数吗?!N怎么可以等于0
看到了ninamomo说的,谢谢,在这再贴下。。 84這題貌似GWD中第四套題第四題 原文給po上來 : For a nonnegative integer n, if the remainder is 1 when 2n is divided by 3, then which of the following must be true? I.n is greater than zero. II.3n = (-3)n III.√2nis an integer. A.I only B.II only C.I and II D.I and III E.II and III 由此可見GWD中n為nonnegative integer,有別於狗主說的非零整數 答案是E 也給各位參考一下 这是前100J里的。个人理解是J妈记错了,所以2是对的,一不对。因为找GWD来看,N可以等于0 -- by 会员 mermaind (2011/1/10 13:23:06)
