A square of a number is calculated by multiplying a number by itself twice. Geometrically, a square is a two-dimensional plane that has equal sides.
\nArea of a square = Side \u00d7 Side
\nSquare number = a \u00d7 a = a\u00b2<\/p>\n
1, 4, 9, 16, 25, 36, 49, 64, etc. are some of the examples of the number for a square of a number. If S is a number that formed by multiplying a by two times, then S is called the square of a number. For example, 16 is a number then it can write as 4 . 4 where 4 is the natural number and 16 is the square of a number. Also, 42 is a number and it is the multiplication of 7 and 6. However, 42 is not considered as a square of a number. Square numbers are also treated as perfect square numbers.<\/p>\n

Check the below examples to understand which numbers are called squares of a number.<\/p>\n
The square of a negative number always a positive number.<\/p>\n
A number is multiplied by itself to form a square of a number. Thus, the number with exponent 2 is called the square number.
\nExample:
\n\\(\\frac { 3 }{ 7 } \\) \u00d7 \\(\\frac { 3 }{ 7 } \\) = (\\(\\frac { 3 }{ 7 } \\))\u00b2 = \\(\\frac { 9 }{ 49 } \\)
\nHere \\(\\frac { 9 }{ 49 } \\) is the square of \\(\\frac { 3 }{ 7 } \\).
\n0.2 \u00d7 0.2 = (0.2)\u00b2 = 0.04
\nHere 0.04 is the square of 0.2.<\/p>\n
Check out the properties of Square Numbers given below to completely understand the Square concept.<\/p>\n
1. If the numbers 2, 3, 7, or 8 present in the unit’s place, then the number will not become a perfect square. Therefore, the numbers that end with 2, 3, 7, or 8 will never become a perfect square.
\n2. The number ends with even zeros becomes perfect squares. Also, the numbers with an odd number of zeros will never become a perfect square.
\n3. Square of even numbers always an even number and square of odd numbers always an odd number.
\n4. If the natural numbers that are more than one are squared, then it should be either of multiple of 3 or more than the multiple of 3 by 1.
\n5. Also, if the natural numbers that are more than one are squared, then it should be either of multiple of 4 or more than the multiple of 4 by 1.
\n6. If the unit’s digit of the square of a number is equal to the unit\u2019s digit of the square of the digit at the unit\u2019s place of the given natural number.
\n7. If there are n natural numbers, say x and y such that x\u00b2 = 2y\u00b2.
\n8. For every natural number n, we can write it as (n + 1)\u00b2 \u2013 n\u00b2 = ( n + 1) + n.
\n9. For any natural number, say\u201dn\u201d which is greater than 1, we can say that (2n, n\u00b2 \u2013 1, n\u00b2+ 1) should be a Pythagorean triplet.
\n10. If a number n is squared, it equals the sum of first n odd natural numbers.<\/p>\n","protected":false},"excerpt":{"rendered":"
