What are the numbers 1 4 9 16 25 called
Perfect squares. When an integer is multiplied by itself, it results in a perfect square. When we square integers like 1, 2, 3, 4, 5, …, we obtain 1, 4, 9, 16, 25, … . Hence, the given numbers which are obtained by squaring the integers are known as perfect squares.
Why are 25 and 9 called perfect squares
Perfect Square Numbers
We know that the square of a number is that number times itself. In other words, the perfect squares are the squares of the whole numbers such as 1 or 12, 4 or 22, 9 or 32, 16 or 42, 25 or 52 and so on.
What is a perfect square up to 25
As you can see, the square numbers follow a pattern. So, 1, 4, 9, 16, and 25 are all square numbers because they can be expressed as 1 x 1, 2 x 2, 3 x 3, 4 x 4, and 5 x 5. Note that a perfect square must be a positive integer—You can't have a negative perfect square or a fractional perfect square.
Why 25 is not a perfect square
25 is a perfect square. 25 is a natural number, and since there is another natural number 5, such that 52 = 25, 25 is a perfect square. Since 25 is a natural number and the square root of 25 is a natural number (5), 25 is a perfect square.
