With perfect squares the number is usually easier to guess and check than calculate, as calculating is a much longer and more complicated process known to few. Guessing and checking may also involve breaking the perfect square down into smaller squares, such as sqrt(5184)-->sqrt(9*576)-->3*24=72, which is also done in large part by conjectures.
Squares to about 25 are useful and easy to memorize, as are the cubes of up to about 10.

What is the difference between perfect and nonperfect square roots?
Perfect square roots are square roots that have a whole number that can go into it perfectly. Nonperfect square roots are square roots that have decimal numbers going into it. Example: Perfect Square Root: 144- Square Root: 12 Nonperfect Square Root: 24- Square Root: About 4.89
Is 224 a perfect square?
To determine if 224 is a perfect square, we need to find its square root. The square root of 224 is approximately 14.96. Since the square root is not a whole number, 224 is not a perfect square. Perfect squares are numbers that are the result of an integer multiplied by itself, such as 9 (3x3) or 16 (4x4).
Is square root are whole numbers?
Very rarely. Square roots are only whole numbers for perfect squares.
Why isn't 28 a square number?
28 is not a perfect square. A perfect square is an integer that is the square of another integer. 9 is a perfect square; it equal to 3 squared, or 3 X 3. Often, such numbers are called simply square numbers. While 28 is not a perfect square, it is a square number in the sense that it has a square root. by definition, the square root of 28 times itself equals 28.

Is the square root of any composite numbers rational?
Yes, of some; the square root of any perfect square is rational - for example, the square root of 4, of 9, of 16, etc.On the other hand, if your "composite number" is not a perfect square, then its square root is irrational.
What square numbers below 100 are also prime numbers?
A [perfect] square number, by definition, has a factor which is its square root. As a result it CANNOT be a prime!
