For a digit to end with 0 it should have both 2 and 5 as a factor.
After factorizing 4 you get 4= 2*2
=2^2
Therefore 4^n= 2^2*n
It only has 2 as a factor and 5 is missing.
Hence any number of the form 4^n (where n is any natural number) cannot end with the digit zero.
Hope this helps you:)

when n=1,2,3,4
than 4n will be 4×1=4
4×2=8
4×3=12
4×4=16
Hence 4n can't end with 0 or 5
