已知K能被2、3、15整除,即K是30的倍数(2、3、15的最小公倍数为30),记K = 30n(n为整数)。 **逐项分析**: - **A) K +5** = 30n + 5。30n是偶数,加5后为奇数,无法被2整除。 - **B) K +15** = 30n +15 = 15(2n +1)。此为15的倍数(能被3、15整除),但2n+1为奇数,整体...

divisible到底是能被除尽还是整除的意思题目是这样的说n is divisible by both 5and 7 then n must also be divisible by 但是我觉得要是说是像字典里一样解释为除尽的话 那不是应该也能被70除尽么? 答案 能被5和7除尽的必定能被35除尽,但不一定能被70除尽,要能被70除尽,需要同时能被5,7,2除尽相...
