👉奇数和偶数 Odd and Even Integer 0是偶数 两个偶数的和为偶数 两个奇数的和为偶数 一奇一偶的和为奇数 偶数的乘积永远为偶数 奇数的成绩永远为奇数 👉质数和合数 Prime and Composite Number 质数是有且只有两个正因数(1和本身)的正整数。
From (1),we can know that x^2+x=y^2+2y.Because x is an odd integer,x^2 is an odd integer too.So the resuit of x^2+2 is an even integer.That is to say y^2+2y is an even integer.If y is an odd integer,y... 分析总结。 单独就是充分的扫码下载作业帮搜索答疑一搜即得...
