99^5+99^4+1是质数还是合数
人气:470 ℃ 时间:2020-05-21 07:19:15
解答
令a=99
a^5+a^4+1
=a^5+a^4+a³-(a³-1)
=a³(a²+a+1)-(a-1)(a²+a+1)
=(a²+a+1)(a³-a+1)
所以是和数99^5+99^4+1的质因数是什么(a2+a+1)(a3-a+1)a=99,自己计算
推荐
1999是素数还是合数?
当a分别是1、2、3、4、5时,6a+1是质数还是合数?
在1、2、3、4、5…中除了质数以外都是合数._.(判断对错)
1999!+1是质数还是合数?(1999的阶乘加1的和是质数还是合数?)
当a分别是1、2、3、4、5时,6a+1是质数还是合数?
