Step-by-step explanation:
For the number 4n to end with digit zero for any natural number n, it should be divisible by 5. ... But it is not possible because 4n=(2)2n so 2 is the only prime in the factorisation of 4n. Since 5 is not present in the prime factorization, so there is no natural number n for which 4n ends with the digit zero.
