Question

check whether expansion of (252)^n , can end with zero for any n as natural number ..

Answer 1

no it will never end with 0 as 252 does not contain 5 as its factor

Answer 2

Answer:

In the prime factorisation of 252, 5 is not a prime factor of 252 so the number will not end with a zero. And for a number to end with 0, it is required for 2 and 5 to be the prime factors.
