Odd
Assuming you know that your number is a perfect square, the square root of an even number is even, and the square root of an odd number is odd.
An odd number.
If by 'perfect number' you mean 'perfect SQUARE', then yes. 49 is an odd number and a perfect square.
All nonzero numbers have factors. Some factors are even numbers, some factors are odd numbers.
Odd. I determined my answer by looking at the number of factors of a square number.
The set of odd whole numbers is countably infinite. It's cardinality is aleph null.
A perfect square has an odd number of factors.
1 is odd and a perfect square.
No. Perfect square numbers have an odd number of factors.
No, all perfect square numbers are not even numbers. Eg. the square of 3 is 9. (32=9) To generalize the proof: If p is odd then p=2n+1 and p2=(2n+1)2=4n2+4n+1=2(2n2+2n)+1 So odd numbers have odd square
-1 is an odd number but not a perfect square.
