Question

For what value of ‘n’ would 4n end with zero?


  1. It will not end with zero for any value of n.

  2. 10

  3. 0

  4. Can’t say


Solution

The correct option is A

It will not end with zero for any value of n.


4n=22n
Now, if a number ends with zero, it should be divisible by 5.
One of the prime factors will be 5.
But 4n is not divisible by 5, therefore it will never end with zero.
