Question

If N is a natural number check whether 5^n is a number ends with zero??....Give ur explanation ​

Answer 1

Answer:

if the number 5n,for any n were to end with the digit zero then it would be dividable by 2 and 5 that is the prime factorization of 5n would contain the prime 2 this is not possible because 5n so only primes in the factorization of 5n is 5 only . therefore there is no natural number n for which 5n ends with digit zero.
