Ifnis a positive integer, what is the remainder whenis divided by 5? 选项: A、1 B、2 C、3 D、4 答案: E 提问列表 提问: 这题我的想法是3的幂次方末尾数是3,9,7,1,然后3^8n+3就是末位为7再加2为9,因为除5看末位就可以,所以余4,但是如果除以其他的数比如3,7等怎么办呢?
解析 A 5+10+15+20+1+1+1+1+1=5+10+15+20+5. Since every term is divisible by 5, the remainder is 0. 5+10+15+20+1+1+1+1+1除以5时,余数是多少( )? A.0 B.1 C.2 D.4 5+10+15+20+1+1+1+1+1=5+10+15+20+5.因为每项都可以被5整除,所以余数是0. 故选A....
