**Solution: To **Check whether **5**^{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

It can be observed that 2 is not in the prime factorisation of 5^{n}.

Hence, for any value of n, 5^{n} will not be divisible by 2.

Therefore, 5^{n} cannot end with the digit 0 for any natural number n.
