Thanks for following up on the line of thought of the question.

The square in the conclusion was a typing error. Thanks for the edit which corrected it.

comment Math Symbols for “Must be Finite”
Interesting so although N's cardinality is countably infinite because there is no finite number to accurately describe it, we use n ∈ N to describe a finite number.

@Mark Bennet n ∈ N, because it is countable infinte?

Yes maybe.. But at least "must be finite" should be expressable in math shortags if I may call them so, no?

Why the downvotes? What did I say wrong. In fact this is a trivial question, but yet it is something I saw as a legit question in an actual exam, baffled by its simplicity, I wanted to make sure that I am not the only one. So don't shoot the messenger.

Thanks for your answers. @MattAllegro why don't you post a reply where you elaborate on the bijective image idea. I would give you the answer then.
