No, it is not.
Incidentally, is a number p is prime then its 2 factors are 1 and p. Their sum is p+1.
If p is a perfect number then this sum must be 2p.
That is, p+1 = 2p or p = 1.
But 1 is not a prime. So no prime can be a perfect number and since 13 is prime, it cannot be a perfect number.
For a number to be a perfect square, the number's square root has to be a whole number. 9 is a perfect square because its square root is a whole number, 3. If the square root of the number is a decimal, then it is not a perfect square. For example, 13 does not divide evenly so it not a perfect square.
It is both.13 is the square of +/- 3.6056, approx. However, since it is not the square of an integer, it is not a perfect square.It is also the square root of 169.
The square root of 13 is irrational. All square roots of whole numbers are irrational unless the number is a perfect square.
Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".Then the number is called a "perfect square".
No, √13 is an irrational number. Only perfect squares have whole numbers square roots, they are 1², 2³, 3², 4², ... which are 1, 4, 9, 16, ...
No but it is a perfect square number because its square root is 13
-1 is an odd number but not a perfect square.

The square root of 175 is 13.23 (2 decimal places) so it is not a perfect square number. The closest perfect squares are 169 (13 squared) and 196 (14 squared).
The sum of the 1st perfect number and 2nd perfect number is. . . 34!
Thirteen does have a square root, and in that sense it is a square number. But thirteen is not a perfect square. There is no integer which, when squared, will give thirteen.
The square root of 13 is irrational. All square roots of whole numbers are irrational unless the number is a perfect square.

If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.
