1. the power of any number is a multiple of itself

   let us give the values of n

   6,6×6,6×6×6…. 6 = 2 × 3

   6 contains only two factors 2 and 3

   but a digit to end with zero we require 5 as a factor

   hence 6 to the power of n cannot end with the digit 0 for any natural number n

2. . 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.
