Show that 9n cannot end with digit 0

WebAug 23, 2024 · Best answer If any number ends with the digit 0 or 5, it is always divisible by 5. If 12n ends with the digit zero it must be divisible by 5. This is possible only if prime factorisation of 12n contains the prime number 5. 12 = 2 × 2 × 3 = 22 × 3 ⇒ 12n = (22 × 3)n = 22n × 3n Since its prime factorisation does not contain 5. Web$\begingroup$ @Git: Of course induction is not impossible to avoid: all you need is some simple axioms about summations, and Josue shows how to make the proof. You can, of course, add induction to anything you want (you used plus? you must have inducted over the successor function!), but that doesn't mean induction was there in the original argument. …
