Question

check whether 12 and can end with the digit 0 for any natural number N​

Answer 1

let us suppose 12N ends with the digit 0 for some n natural number N.

Hence,12 N is divisible by both 2 and 5

But,prime factorisation of 12 N are (2x2x3)N

=> it is clear that in prime factorisation of 12 N there is no place for 5 .

Hence,our supposition is wrong.

Therefore there doesn't exist any natural number N for which 12 ends with the digit 0.
