Answer: 2, 3, 5, 7
Prime numbers are positive integers greater than 1 that have no positive integer divisors other than 1 and themselves. In other words, prime numbers are numbers that are only divisible by 1 and themselves.
Examples of prime numbers are:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, and so on.
Prime numbers play an important role in number theory and cryptography, and they have many interesting properties and applications in various fields of mathematics and science.
The prime numbers less than 10 are 2, 3, 5, and 7.
So, the prime numbers x that make the inequality x < 10 true are:
2, 3, 5, and 7.
All of these numbers are less than 10 and are prime. Therefore, the solution set for x is {2, 3, 5, 7}.
