To be a perfect square, each factor must appear an even number of times. Then (100a+b) must be a multiple of 11, which in this case is achieved by making that a+b=11. So, the possibles a and b are 9 and 2, 8 and 3, 7 and 4, 6 and 5, or the opposite order.

Meaning. Informally: When you multiply a whole number times itself, the resulting product is called a square number, or a perfect square or simply "a square." So 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers. (or n2), where n is any whole number.

As decimal expansions The square roots of the perfect squares (0, 1, 4, 9, 16, etc.) are integers. In all other cases, the square roots of positive integers are irrational numbers, and therefore their decimal representations are non-repeating decimals.

How to Tell If a Number Is a Perfect Square. You can tell if a number is a perfect square in a couple of different ways. First of all, if you create a square by multiplying two equal integers by each other, then the product is a perfect square. So, 1 * 1 is a perfect square.

Please note that all the perfect square numbers end with 0, 1, 4, 5, 6 or 9 but all the numbers with end with 0, 1, 4, 5, 6 or 9 are not perfect square numbers. Example, 11, 21, 51, 79, 76 etc. are the numbers which are not perfect square numbers.

If you have a whole number and multiply it by itself, like 7X7= 49, then the square root of 49 would be 7. This is called a perfect square. ... The square root of 52 is an imperfect square. There are not a whole number times itself that equals 52.

Is 29 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 29 is about 5.385. Thus, the square root of 29 is not an integer, and therefore 29 is not a square number.
