These are the integers which can be evenly divided into 9; they can be expressed as either individual factors or as factor pairs. In this case, we present them both ways.
A prime factorization is the result of factoring a number into a set of components which are all prime numbers. This is generally written by showing 9 as a product of its prime factors. For 9, this result would be:9 = 3 x 3
No! 9 is not a composite number. None of the two factor pairs were the same number. A composite number must be formed as the product of a smaller positive integer.
Yes! 9 is a square. Its square root is an integer, specifically 3.
This number has 3 factors: 1, 3, 9
More specifically, shown as pairs...
(1*9) (3*3) (9*1)
