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.

Two.
No
The two smallest prime numbers are 2 and 3. So, the smallest number that is a product of two different primes that are squared is 22 x 32 = 36.
The products of the primes are the composites.

95 is the product of two primes, 5 and 19.
Two.
The largest integer that is not the product of two or more different primes would be the largest prime number. Because there are an infinite number of prime numbers, there is no largest integer that is not the product of two or more different primes.
No
It is very difficult to factorise a number that is the product of two very large primes but, given one of these primes, it is very easy to verify the result and to find the other prime.It is very difficult to factorise a number that is the product of two very large primes but, given one of these primes, it is very easy to verify the result and to find the other prime.It is very difficult to factorise a number that is the product of two very large primes but, given one of these primes, it is very easy to verify the result and to find the other prime.It is very difficult to factorise a number that is the product of two very large primes but, given one of these primes, it is very easy to verify the result and to find the other prime.

It is the product of two primes and so is a composite.

A composite number. The product of two primes is sometimes called a semiprime.
