You say, "144 is a square number. Divide it by 4 and you get 36, which is also square. Does this happen with any other square numbers?"
The question is ambiguous. Clearly 100, for instance, is a square which, when divided by 4 gives you 25 which is also a square. So indeed any even square must have the property that dividing it by 4 gives you another square. To what property does the word "this" in the question refer?
