Question

check whether 15^n can end with the digit o for any natural number n​

Answer 1

Answer:

No

Step-by-step explanation:

As 15 is not in the form of 2^n and 5^m.

Answer 2

This means the prime factorization of 15ⁿ should contain prime factors 2 and 5. It does not have the prime factor 2 but have 3 and 5, Since 2 is not present in the prime factorization, there is no natural number nor which 15ⁿ ends with digit zero. So,15ⁿ can not end with digit zero
