A prime number is a positive integer with two factors: one and the number itself. A squared number is any integer multiplied by itself. With the exception of 1, all squared numbers are composite.

When you square a number, the final digit is the final digit of the 'one's' number squared. Since the only single digit numbers squared which ends in 6 are 4 and 6, the answer is either 4 or 6 (a calculator tells me it is 6) 0 squared is 0. All numbers ending in 0 when squared will end in 0. 1 squared is 1. All numbers ending in 1 when squared will also end in 1. 2 squared is 4. All numbers ending in 2 when squared will end in 4. 3 squared is 9. All numbers ending in 3 when squared will end in 9. 4 squared is 16. All numbers ending in 4 when squared will end in 6. 5 squared is 25. All numbers ending in 5 when squared will end in 5. 6 squared is 36. All numbers ending in 6 when squared will end in 6. 7 squared is 49. All numbers ending in 7 when squared will end in 9. 8 squared is 64. All numbers ending in 8 when squared will end in 4. 9 squared is 81. All numbers ending in 9 when squared will end in 1. So square numbers can only end with 0, 1, 4, 5, 6 or 9.

All prime numbers are rational.

There is no need to do prime factorization as prime numbers are already prime.

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 !

they are both numbers

The only prime numbers with squares less than 20 are 2 and 3 Numbers containing 2 squared : 4, 8, 12, 16 Numbers containing 3 squared : 9, 18

A prime number is a positive integer with two factors: one and the number itself. A squared number is any integer multiplied by itself. With the exception of 1, all squared numbers are composite.

Because they are all squared prime numbers each having a common factor of 1.

All composite numbers do. All prime numbers are already prime.

When you square a number, the final digit is the final digit of the 'one's' number squared. Since the only single digit numbers squared which ends in 6 are 4 and 6, the answer is either 4 or 6 (a calculator tells me it is 6) 0 squared is 0. All numbers ending in 0 when squared will end in 0. 1 squared is 1. All numbers ending in 1 when squared will also end in 1. 2 squared is 4. All numbers ending in 2 when squared will end in 4. 3 squared is 9. All numbers ending in 3 when squared will end in 9. 4 squared is 16. All numbers ending in 4 when squared will end in 6. 5 squared is 25. All numbers ending in 5 when squared will end in 5. 6 squared is 36. All numbers ending in 6 when squared will end in 6. 7 squared is 49. All numbers ending in 7 when squared will end in 9. 8 squared is 64. All numbers ending in 8 when squared will end in 4. 9 squared is 81. All numbers ending in 9 when squared will end in 1. So square numbers can only end with 0, 1, 4, 5, 6 or 9.

All the numbers above 2 that are the squares of odd primes have exactly 3 factors: 1, the odd prime, and the odd prime squared. 4, 9, 25, 49, 81, 121,...
