Q
Q: If A = {x | x is a prime number less than 10} and B = {2, 3, 5, 7}, what is A?
Solution:
The set A consists of all prime numbers less than 10, which are {2, 3, 5, 7}.
Steps: 4
Show Steps
Step 1: Understand what a prime number is. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.
Step 2: Identify the prime numbers less than 10. These are: 2, 3, 5, and 7.
Step 3: Write down the set A using the prime numbers identified. Set A = {2, 3, 5, 7}.
Step 4: Compare set A with set B. Set B is given as {2, 3, 5, 7}, which matches set A.
