## Why is 20 not a square number?

So now we know the digital root of 20 is 2. Is 2 in the list of digital roots that are always a square root (1, 4, 7 or 9)? Answer: NO, 2 is not in the list of digital roots that are always perfect squares. We can conclude that 20 IS NOT a perfect square and we don’t need to factor!

## What numbers can be shown Square?

Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.
