The digit that goes in the place of one in a number is known as the units digit. i.e. It is the number's rightmost digit. As an illustration, the unit digit for 243 is 3, whereas the unit digit for 39 is 9.

The result of multiplying a number by itself produces a power..A power is usually represented by a base number and an exponent. The base number reveals what number is being multiplied. A little number that is placed above and to the right of the base number, called the exponent, indicates how many times the base number has been multiplied.

Given

9²⁰⁰⁰

Find

last digit of 9²⁰⁰⁰= ?

Solution

The given number is 9.

So every even power of 9 gives 1 as it's unit's place.

For instance, 9⁰ = 1

                      9² = 81

                      9⁴ = 6561

                      9⁶ = 531441

Hence we can notice that for every even power we get 1 on the units place.

9²⁰⁰⁰ is a even power of 9, so we get the units place value as 1.

Therefore the units place digit of 9²⁰⁰⁰ is 1
