Only whole numbers are even or odd, and the square root of 75 is not a whole number.
I cannot see how odd or even will determine the number of digits in the square root. For example:100 is an even number, and its square root is 10 (2 digits)121 is an odd number, and its square root is 11 (2 digits)Maybe the question is not phrased properly for what the questioner is asking.
yes 9 25 49 81 121 All odd numbers squared are odd numbers
"Factors come in pairs, so this is impossible." This statement is false. A number can have an odd number of factors by having the square root as one of the factors. Find a number with 12 factors and a square root.
Yes. Square numbers have an odd number of factors. 49 has three factors.
Look for odd squares. Multiplying odd numbers results in an odd product.
Only whole numbers are even or odd, and the square root of 75 is not a whole number.
Half of all square numbers are odd. They are the ones which are the square of an odd number.

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.
Square numbers have odd numbers of factors.
Square numbers have odd numbers of factors.
Yes, they are. Sketch of proof: Odd square root is a number x of form x = 2n + 1. Square of this root is: x2=(2n+1)2=4n2+4n+1=y, which can be expressed as: y=2(2n2+2n)+1. Let t = 2n2+2n. Then, y=2t+1, which is an odd number.
Square numbers have odd amounts of factors because the square root is listed as a single factor, not a pair of factors. For example, the factors of 25 are 1, 5, 25.
There are infinitely many of them. The square of every odd number will be an odd square number.
The square of any odd number is also an odd number for reasons that should be obvious.
The square root of 21 is not an integer. The concepts of "even" vs. "odd" is only defined for integers.
