Cyclicity of 81

Here we will show you how to find the Cyclicity of 81. First you make the following calculations:

81¹ = 81
81² = 6561
81³ = 531441
81⁴ = 43046721
81⁵ = 3486784401

Then you look at the last digit of each of the numbers you found above: 1 1 1 1 1.

The Cyclicity of any number such as 81 is a sequence of 1 to 4 numbers. You will see that the last digits from the answers above will start repeating themselves. This sequence of numbers that repeats itself is called the Cyclicity of 81.

As you can see, the Cyclicity of 81 has 1 number. The Cyclicity of 81 is
