Answer 1

Step-by-step explanation:

If 15n is divisible by 10 then it can end with digit zero.

If it is divisible by 10, it has to be divisible by 5 and 2 both.

The prime factorization of 15 is 3×5.

15n=(3×5)n

By observation, (3×5)n is divisible by 5 but not by 2.

Hence, 15n is not divisible by 10.

Hence, 15n does not end with digit 0 for any natural number n.
