12 x 14 = 168
The product of two prime numbers will be composite.
Yes, of course. In fact the product of any two numbers is composite unless one of them is 1.
The product of two composite numbers is between 11 and 17. 12 = 2 x 2 x 3, so it cannot be the product of two composite numbers, because there are only three prime factors. 13 is prime. 14 = 2 x 7, so it cannot be the number. 15 = 3 x 5, so it cannot be the number. 16 = 2 x 2 x 2 x 2, so it is the product of two composite numbers, 4 x 4. 16 is the only number that fits. Its prime factors are 2, 2, 2, and 2.
Product of two prime numbers is a composite number. e.g. 2 x 3 = 6, 3 x 17 = 51 etc. But, why the result is a composite number? Definition of composite number makes it much clear: A number which can be expressed as the product of prime numbers is called a composite number. Also, it has more than two factors. So, product of two primes is a composite number.
The product of two prime numbers is always a composite number, and it never is a prime number.
The product of two prime numbers will be composite.
If the number is a product of two composite numbers, it must be 16, which is the product of 4 and 4. The prime factors of 16 are 2, 2, 2, and 2. The smallest composite number is 4, so the smallest possible product of two composite numbers is 4 x 4 = 16.
Yes, of course. In fact the product of any two numbers is composite unless one of them is 1.

composite
No not always because composite numbers can be the product of 2 or more prime factors
When the numbers are relatively prime.
There are no two "last" composite numbers. Just as with prime numbers, and all numbers, they go on for ever and ever and ever and ever ... ... .

Public key encryption is based on composite numbers. In fact it is based on composite numbers which are the product of two very large prime numbers.
The product of two composite numbers is between 11 and 17. 12 = 2 x 2 x 3, so it cannot be the product of two composite numbers, because there are only three prime factors. 13 is prime. 14 = 2 x 7, so it cannot be the number. 15 = 3 x 5, so it cannot be the number. 16 = 2 x 2 x 2 x 2, so it is the product of two composite numbers, 4 x 4. 16 is the only number that fits.
