Your question was =

What will be the digit in the unit’s place of a single digit which belongs to the set of natural numbers, when this number is raised to the power 5?

In order to answer this question,

let us find out the values of the different natural numbers in the ascending order of their powers upto the power 5.

For the natural number 2:

For the natural number 3:

3, 9, 27, 81, 243

For the natural number 4:
