Prime numbers, except 2, are always odd (they would not be prime if they were even cos they would be divisible by 2.) 1 less than any odd number must be an even number.

Q: Why are square numbers one less than a prime number always even?

No, there are no prime numbers that are also square numbers. Prime numbers are only divisible by 1 and themselves, while square numbers have integer square roots. Since the square root of a prime number is not an integer, a prime number cannot be a square number.

Prime numbers cannot be square numbers.

A square number, by definition, cannot be a prime so the answer is there are no such numbers.A square number, by definition, cannot be a prime so the answer is there are no such numbers.A square number, by definition, cannot be a prime so the answer is there are no such numbers.A square number, by definition, cannot be a prime so the answer is there are no such numbers.

Yes.

An oxymoron. Prime numbers can't be square. Square numbers can't be prime. You can square a prime number: 3 x 3 - 32 = 9

Square numbers have too many factors to be prime.

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

No. A prime number is always odd.

Absolutely not. A square number has an integer square root, so by definition it has at least one factor. Prime numbers have no factors

Prime numbers have two factors. All square numbers (other than 1) have more than that.

A [perfect] square number, by definition, has a factor which is its square root. As a result it CANNOT be a prime!

No.
