A. it is divisible by 4 B. it is not divisible by 4 C. we can't make a conclusion D. the claim is false 相关知识点: 试题来源: 解析 B。因为如果一个数能被 4 整除就一定能被 2 整除,现在已知一个数不能被 2 整除,反证可知它也不能被 4 整除。
Hence, if a number is divisible by both 9 and 10 then it is divisible by 90 (5)False. Since 15 and 32 are co-primes and also composite numbers (6)False, as 12 is divisible by 4 but is not divisible by 8 (7)True, as 2x 4 = 8. Hence, if a number is divisible by 8...
