Any even exponent of 3 is a square number.
A number has exactly three factors if and only if it is the square of a prime number.
The factors of 18 are 1, 2, 3, 6, 9, and 18. The only square number of those numbers is 9.
there are an infinite amount of square numbers 4,9,16,25,36,49,64,81,100... A square number is a number multiplied by its self. For example 6 times 6 is 36 so 36 is a square number To Help just add the odd 2 times tables to get each square number. For example: 1=1 1+3=4 1+3+5= 9 1+3+5+7-= 16 1+3+5+7+9= 15 11 12 13 14 15 16 17 18 19 20 carrying on from 100... 121,144,169,196,225, 256, 289, 324, 361, 400!
Perfect squares are positive. A smallest negative number doesn't exist. The four smallest prime numbers are 2, 3, 5 and 7. The smallest perfect square would have to be 2^2 x 3^2 x 5^2 x 7^2 or 44,100

generally you would multiply a number by itself, but i have found out a marvelous trick, and it is pretty easy since I am only a child, but starting with 1, if you add three, you get four, the next square number. then you add five to get nine the next square number, then seven to get sixteen and so on. So in simpler terms you take one and add three to get the next square number, then add five, then seven counting by odd numbers. Here is an equation. the bold numbers are the square numbers and the Italic numbers are the progressing odd numbers.1+3= 4+5= 9+7=16and so on.

The numbers are: (3 +square root of 153) and (3 -square root of 153)
Add successive square numbers. The next number is 57.

An oxymoron. Prime numbers can't be square. Square numbers can't be prime. You can square a prime number: 3 x 3 - 32 = 9

No, square numbers are numbers that are the square of a whole number, such as: 12 = 1; 22 = 4; 32 = 9; etc. The numbers 1, 4, 9, etc. are the square numbers.
There is only one square number, and that is 9.
The two square numbers which add up to 13 are 9 (which is equal to 3 squared), and 4 (which is equal to 2 squared).
