Cyclicity of 90

Here we will show you how to find the Cyclicity of 90. First you make the following calculations:

90¹ = 90
90² = 8100
90³ = 729000
90⁴ = 65610000
90⁵ = 5904900000

Then you look at the last digit of each of the numbers you found above: 0 0 0 0 0.

The Cyclicity of any number such as 90 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 90.

As you can see, the Cyclicity of 90 has 1 number. The Cyclicity of 90 is
