The prime factors of a squared number are the prime factors, if any, of its square root.
No because then it will have more than two factors
91 is neither a prime nor a squared number. It is a composite having the prime factors 7 x 13.
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.
Okay, whoever said that a number can only have an even number of factors IS Wrong Take a prime number and square it. If you square a prime number, the number you get will only have 3 factors. For example, if I squared the number 3, I would get 9. 9 only has three factors: 9, 3, 1 Any prime number squared has Three factors.

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.
Any prime number to the 5th power squared has 11 factors, like 1024 or 59049.
The prime factors of 21 are 3 x 7, so the prime factors of 21 squared are 32 x 72. The factors of 21 squared are 1, 3, 7, 9, 21, 49, 63, 147, and 441.
1,0012 = 1,002,001. The prime factorization of 1,002,001 is:None! 1,002,001 is a prime number. Its only factors are 1 and 1,002,001.
To find the original number when given the prime factors, we have to work backwards. First, we simplify into 2 squared times 3 squared. (2x2) x (3x3) Then we expand the brackets. 4 x 9 = 54 Therefore 54 is the number, with 2x2 and 3x3 as the prime factors.
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 !
