Check whether 6^n can end with the digit 0 for any natural number n

If any number ends with the digit 0, it should be divisible by 10 or in other words, it will also be divisible by 2 and 5 as 10 = 2 × 5

Prime factorisation of 6ⁿ = (2 ×3)ⁿ

It can be observed that 5 is not in the prime factorisation of 6ⁿ.

Hence, for any value of n, 6ⁿ will not be divisible by 5.

Therefore, 6ⁿ cannot end with the digit 0 for any natural number n.
