## 2 to the Power of 55

Reading all of the above, you already know most about 2 to the power of 55, except for its inverse which is discussed a bit further below in this section.

Using the aforementioned search form you can look up many numbers, including, for instance, 2 to the power 55, and you will be taken to a result page with relevant posts.

Now, we would like to show you what the inverse operation of 2 to the 55th power, (255)−1, is. The inverse is the 55th root of 255, and the math goes as follows:

(255)−1

=

=

=

=

2

Because the index of 55 is not a multiple of 2, which means odd, in contrast to even numbers, the operation produces only one value: (255)−1.

Make sure to understand that exponentiation is not commutative, which means that 255 ≠ 552, and also note that (255)-1 ≠ 2-55, the inverse and reciprocal of 255, respectively.
