The number 1 is a perfect square that is equal to the sum of the perfect squares that precede it, as there are no perfect squares before it (0 is not considered a perfect square in this context). Additionally, the number 5 is another perfect square, specifically (2^2), which equals the sum of the perfect squares 0 (which is (0^2)) and 1 (which is (1^2)). However, the most straightforward example is 1.
Yes, in so far as all numbers are squares (of some number). But it is not a perfect square.
A perfect square is indeed a number that can be expressed as the square of an integer. For example, numbers like 1, 4, 9, and 16 are perfect squares, corresponding to the squares of 1, 2, 3, and 4 respectively. The square root of a perfect square is always an integer, making it distinct from non-perfect squares, which have non-integer square roots.
It is a rational number - as are ALL perfect squares.
There is no limit to the number of perfect squares. To find a perfect square, you simply need to pick a number and square it. E.g. 7^2=49, so 49 is a perfect square. As there is infinitely many numbers to pick, and as the larger a number the larger it's square, there are infinitely many perfect squares and they just keep on getting larger!
Well, the basic idea is that every positive number is the square of some number. For example, 2 is the square of a number known as the square root of 2; 3 is the square of a number known as the square root of 3; etc. The "perfect squares" are the squares of integers. That would make all other numbers "non-perfect squares", though this term is not usually used in practice.

It does not matter! There are more numbers that are not perfect squares than there are perfect squares and the universe has not ground to a screeching halt!

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.

A perfect square has an odd number of factors. Factors of numbers always come in pairs -- except for perfect squares. Since the square root of a perfect square is listed only once on the list of factors, it results in a list with an odd number of factors.

A whole number whose square root is also a whole number is called a perfect square. In mathematics, perfect squares are numbers that can be expressed as the product of an integer with itself. Examples of perfect squares include 1, 4, 9, 16, and so on.
Perfect squares will never be irrational numbers. A perfect square is the result of multiplying an integer by itself, which always yields a rational number. Since the square root of a perfect square is an integer, perfect squares are always rational. Thus, they cannot be irrational.
"Perfect square" means that you square a whole number. Sometimes simply called "square" or "square number". "Difference of two squares" is the result of subtracting one such square from another. In most cases, the difference will not itself be a square.
If the number inside the radical is a perfect square or a ratio of perfect squares.
