(1)B(2)A (1) ais an even number and is an odd number. Even + odd = odd. Therefore, we choose B. (2) ais an even number; therefore 3ais an even number. is an odd number; therefore, 2is an even number. Even + even = even. Therefore, we choose A.反馈...
a2−1=( ). (英汉小字典:odd number奇数;there must exist一定存在;such that使得) A. 3nB. 5nC. 8nD. 16n相关知识点: 试题来源: 解析 C 如果a是奇数,那么一定存在一个整数n使得a2−1等于( ). 因为a是一个奇数,故可令a=2n+1(n∈Z),则 a2−1=(2n+1)2−1=4n2+4n=4n(n+1). 又...
Under the rules of parity, is zero even or odd? As a whole number that can be written without a remainder, 0 classifies as an integer. So to determine whether it is even or odd, we must ask the question: Is 0 divisible by 2? A number is divisible by 2 if the result of its ...
