1+4+9=14
The 1st 3 square numbers are 1 (1x1), 4 (2x2) and 9 (3x3)
There is no "the" square number. 225, 256 and 289 are THREE square numbers between 200 and 300.
The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.
A square number is any number multiplied by itself. 1 is a square number, since 1 x 1 = 1. 2 is not, since there is no integer that you can multiply by itself to get 2. 4 is the next square number, since 2 x 2 = 4. Squaring 3, 4, and 5 give the next three square numbers: 9, 16, and 25. To get the first thousand square numbers, take each of the first thousand natural numbers (1, 2, 3, ... 1000) and multiply them by themselves. This will produce the first thousand square numbers, ranging from 1 (1x1) to 1,000,000 (1,000 x 1,000).

Three of them.
There are (not counting 1) three square numbers between 1 and 20.
There are no rational numbers between sqrt(-26) and sqrt(-15). The interval comprises purely imaginary numbers.
The 1st 3 square numbers are 1 (1x1), 4 (2x2) and 9 (3x3)
9, 16, and 25 are square numbers.
102 = 100 which is the first possible three digit number that is a perfect square. 312 = 961 which is the last possible three digit number that is a perfect square. So there are 22 three digit positive numbers that are perfect squares.
There are three of them with exactly five factors.
(√10) × 3 lines between 9 and 10.
6 and 8. 4 is a square, which can be considered as a special case of a rectangle.
The square roots of three are examples of irrational numbers.
the answer is 120 because the first three prime numbers are 2,3,5 and the first three composite numbers are 4,6,8.
The first three prime numbers are 2,3 and 5.
