Nevertheless, on the second floor there is one window which is not boarded; sometimes in the late afternoon when the heat is at its worst a hand will slowly open the shutter and a face will look down on the town. It is a face like the terrible dim faces known in dreams -- sexless ...
If a is odd number,the there must exist an integer n such that a2-1=( )A.3nB.5nC.8nD.16n 答案 ∵a是奇数,∴设a=2n-1(n≥2),∴a2-1=(2n-1)2-1=[(2n-1)+1]×[(2n-1)-1]=2n(2n-2)=4n(n-1)如果n是偶数,则必然有-x使n=2x,原式=8x(n-1);如果n是奇数,则(n-1)为偶...

(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n和n+1是两个连...
