A number is a perfect square when you can directly extract its square root in whole numbers and without approximation. When you subject a certain number to a radical sign, you can extract its square.
Example: 25 is a perfect square. it's square root is 5, since 5 x 5 is equal to 25

How do you know a number is a perfect square?
When it can be square rooted
If you do not know the square root of a really big number how do you know if its rational?
Assuming your number is an integer: if the number is a perfect square, the number is of course an integer, and therefore rational. If the number is NOT a perfect square, it is irrational.
How should you know about perfect squares?
If you have a number like 12 and you multiply it by the same number: 12 and the answer you get is a whole number, then the whole number is the perfect square.
How can a make a batch file to know if a number is not a perfect square?
a number is a perfect square when you can directly extract its square root in whole numbers and without approximation. when you subject a certain number to a radical sign, you can extract its square. example: 25 is a perfect square. it's square root is 5, since 5 x 5 is equal to 25
How we know which smallest number is subtracted to get a perfect square?
Find the square root of the number.Take the integer part of the answer.Square the integer part.Subtract this square from the original number.
