The product of the two prime numbers is 111. The two prime numbers are () and ()
111=3×17
The product of the two prime numbers is 111, which are (3) and (37) respectively
Is there 111 in prime number
No, 111 = 3 * 37, so it's a composite number
When n is an integer, is the value of formula n ^ 2 + N + 11 necessarily prime?
Why? The specific analysis process
When n is an integer, is the value of formula n ^ 2 + N + 11 a prime number? A: not necessarily! When n = 1,2,3,. 9, the value of formula n ^ 2 + N + 11: 13,17,23,..., 101 is a prime number. When n = 10, the value of formula n ^ 2 + N + 11 = 121 = 11 * 11 is not a prime number
