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.
1 and 9 are both square numbers, and 9 - 1 = 8.
They are square numbers.
1, 4, and 9
1 and 9
square numbers are the numbers that are... 1x1=1 2x2=4 3x3=9 4x4=16 ..... 1,4,9,16,25,36,49,64,81,100,121,144.........
the first 4 square numbers are 1, 4, 9, and 16.
4, 9, 16, 25, and 36 are the square numbers between 1 and 40.
4 & 9
The first 5 square numbers are 1, 4, 9, 16, and 25.
No, a square root doesn't have to be a whole number. The square root of 2.25 is 1.5. It could be said that most square roots are not whole numbers. Take just the first few integers (counting numbers). Find the square roots of the numbers 1 through 10 and you'll find three of the numbers have whole number square roots (1, 4 and 9). The other seven don't. For the numbers 11 through 20, there is only 1 number with a whole number square root (16).
