Expert Answer:

Hello,
 
Nature of 4N  will depend on nature of "N".
If N is a natural number, then 4N will also be a natural number, and it will never end with 0.
because as we see, 
41 = 4
42 = 16
43 = 64
44 = 256
...
 
and so on. The last digit will always repeat as above. 
 
if "N" is an integer, then 4N is not going to be natural always.
For example:
4-1 = 0.25
 
Hence, we need to properly define the set of  values that N can take.
