A perfect square has an odd number of distinct factors, because two of its factors are the same number.
No. Square numbers (or perfect square numbers) are squares of integers. The perfect square numbers are 1, 4, 9, 16, 25, 36 ... 20 is not in the series.
A perfect square
In the appropriate domain, all numbers are square numbers. Perfect square numbers are numbers that are obtained by multiplying an integer by itself.
Square numbers * * * * * Although "perfect square numbers" is more descriptive.
It's a perfect square.
None, although "perfect square" tends to be used for whole numbers.
The square root of every perfect square is an integer. However, there are also square roots of numbers that are not perfect squares.
no, 10 is not a perfect square. in order for a number to be a perfect square, you have to see if the numbers that are multiplied to get it are the same. for example: 2x2=4; 4 is a perfect square. 12x12=144; 144 is also a perfect square 5x2=10 or 10x1=10. 10 isn't a perfect square because 5 and 2, and 10 and 1, are different numbers.
All numbers have factors. Some factors are perfect squares. We call these perfect square factors. 9 is a perfect square factor of 27.
no. 64 is a perfect square and so is 100 but because the property that connects those two numbers is addition it is not a perfect square.
Non-perfect square numbers are numbers that are not formed from the square of a number. 12, 13, 14, 21, 99, etc, are all non-perfect square numbers because when you square root them you do not get a whole number, which means they are not formed by any whole number, x, being squared (x^2).
