问题 32010+42011 +82012 的个位数为()。
选项 A. 9 B. 8 C.6 D.4
答案 A
解析 本题考查乘方尾数问题。一个自然数幂的尾数是以4为周期循环的,则原式的尾数相当于32+43+84的尾数,即9 + 4 + 6的尾数,故正确答案是A项。

Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option).
