Excluding 1...
4 = 2 + 2
9 = 7 + 2
16 = 13 + 3
25 = 23 + 2
36 = 31 + 5
49 = 47 + 2
64 = 61 + 3
81 = 79 + 2
100 = 97 + 3
121 doesn't work either...
144 = 141 + 3
No, square numbers have an odd number of factors.
no, every number is a real number --- There are numbers that are not real numbers. They are called imaginary numbers, and have the property that when they are squared, the result is negative. The square root of -1 is called i, and the square root of any other negative number is i times the square root of the absolute value of the number. So the square root of -4 is 2i.
Every square number (except 1) is composite. Prime numbers only have two factors, one and the numbers themselves. Since square numbers also have at least the square roots as factors, they have to be composite.
All odd numbers are in the form of (2n + 1) form some integer n. (2n + 1) can be expanded into (n+1)^2 + n^2, which is the difference of two squares.
No. Consider 15: 1,3,5,15 Every positive whole number has an even number of factors, unless the number is a perfect square.
All numbers can make a square. Every real number makes a positive real square. Every rational number makes a rational square. Every integer makes a perfect square.
Every whole number
There are infinitely many of them. The square of every odd number will be an odd square number.
The square of every positive or negative even whole number is a positive even whole number. The square of every positive or negative odd whole number is a positive odd whole number. There are an infinite number of each kind.
In the complex field, every number is a square so there are no numbers that are not squares. If the domain is reduced to that of real numbers, any negative number is not a square. However, the term "square numbers" (not number's!) is often used to refer to perfect square numbers. These are numbers that are squares of integers. Therefore the squares of fractions or irrational numbers are non-squares.
No, square numbers have an odd number of factors.
Infinitely many, since every number in that range is a square of some other number. There are 7 perfect square numbers.
Asking for a list for "every number" really doesn't make sense; there are infinitely many numbers, even if you are referring only to whole numbers. You can get the square root of specific numbers on any calculator.

Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.
