Answer 1

Answer:

Here is your answer hope it is helpful

Step-by-step explanation:

As we know that

15n = (3 x 5)n   =  3n x 5n

The prime factorization of 15 doesn't have a 2 and 5 as its factor. So, its factorization will never end in 10 as a number ending in 10 must have a factors as 5 and 2.

So, 15n will never end in zero as 15 doesn't has 2 as a factor.
