Question

Show that any number of the form 4^n, n €N can never end with the
digit 0.​

Answer 1

Answer:

For a digit to end with 0 it should have both 2 and 5 as a factor. 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.

Answer 2

Answer:

n belong to natural numbers

if n = 0 then

4^0

= 1
