To write the set {x | x is a prime number which is a divisor of 60} in roster form, we first need to identify all the prime numbers that are divisors of 60.
First, let’s list all the divisors of 60:
- 1
- 2
- 3
- 4
- 5
- 6
- 10
- 12
- 15
- 20
- 30
- 60
Next, we identify which of these divisors are prime numbers. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself.
From the list above, the prime numbers that are divisors of 60 are:
- 2
- 3
- 5
Therefore, the set in roster form is:
{2, 3, 5}
