Hii There!!
Any positive integer ending with zero is divisible by 5.
Prime factorization of 15^n =(3×5)^n.
By the uniqueness of Fundamental theorem of Arithmetic.
As it does not occur in the prime factorization of 15^n for any natural number n.
Therefore, 15^n can never end with digit zero for any natural number.
Hope it helps
