the two prime numbers will be factors of that number, which would make that number a composite number

No, reversing the order of the digits of a two-digit prime number does not always result in a prime number.

No. That isn't possible: A prime number, by definition, has no smaller factors. A square number does have a smaller factor - the number that is squared.

The product of two prime numbers is always a composite number, and it never is a prime number.

A prime number is only divisible by itself and 1... A squared number is a multiple of itself - and thus is not a prime number !

The only other single-digit number higher than 5 which is a prime number is 7 - 9 is equal to 3 squared, and is thus not a prime number.

Each ascending number is equal to the square of the next prime number multiplied by (the prime number plus one). In this case, 11 squared x 12 = 1452. Therefore, the next number in the sequence is equal to 13 squared x (13 + 1) = 13 squared x 14 = 2366.Following this, the next number would be 17 squared x 18 = 5202.

Yes.
