Explanation in exercise 2

1. Is 32 a Composite Number? Yes, since 32 has more than two factors i.e. 1, 2, 4, 8, 16, 32. In other words, 32 is a composite number because 32 has more than 2 factors.
2.  13 is a prime number. The number 13 is divisible only by 1 and the number itself. For a number to be classified as a prime number, it should have exactly two factors. Since 13 has exactly two factors, i.e. 1 and 13, it is a prime number.
3. 37 is a prime number. The number 37 is divisible only by 1 and the number itself. For a number to be classified as a prime number, it should have exactly two factors. Since 37 has exactly two factors, i.e. 1 and 37, it is a prime number.
4. since 45 has more than two factors i.e. 1, 3, 5, 9, 15, 45. In other words, 45 is a composite number because 45 has more than 2 factors.
5. Is 72 a prime number? "No, 72 is not a prime number." Since 72 has more than 2 factors i.e. 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72, it is a composite number.
