If p is a prime number greater than 2, what is the value of p ?
(1) There are a total of 100 prime numbers between 1 and p + 1.
(2) There are a total of p prime numbers between 1 and 3,912.
怎么算出来的啊....
本菜以为,完全不需要算出来,只需要确认,一个一个质数列举下去,总有一天逮到P
板上钉钉,不需要其他条件,故选D
听听NN看法
(1) There are a total of 100 prime numbers between 1 and p + 1.
1,2,3,5,7,11.....明显的是大于2的质数都是奇数 所以如果有100个质数between 1 and p+1 而p又是一个大于2个质数 所以第100个质数必然就是P本身 那么p的值就可求了.具体自己写 多到死.....
(2)There are a total of p prime numbers between 1 and 3,912.
这个P很确定啊,大于1小于3912的质数就是那么多
所以D....
