2 to the Power of 66

Reading all of the above, you already know most about 2 to the power of 66, 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 66, 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 66th power, (266)−1, is. The inverse is the 66th root of 266, and the math goes as follows:

(266)−1
= \sqrt[66]{2^{66}}
= 2^{66/66}
= 2^{1}
= 2

Because the index of 66 is a multiple of 2, which is even, in contrast to odd numbers, the operation produces two results: (266)−1 = \pm 2; the positive value is the principal root.

Make sure to understand that exponentiation is not commutative, which means that 266 ≠ 662, and also note that (266)-1 ≠ 2-66, the inverse and reciprocal of 266, respectively.
