What is 2 to the 18th Power?
2 to the 18th power is conventionally written as 218, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 2^18.
218 stands for the mathematical operation exponentiation of two by the power of eighteen.
As the exponent is a positive integer, exponentiation means a repeated multiplication:
The exponent of the number 2, 18, also called index or power, denotes how many times to multiply the base (2).

2 to the Power of 18
Reading all of the above, you already know most about 2 to the power of 18, 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 18, 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 18th power, (218)−1, is. The inverse is the 18th root of 218, and the math goes as follows:
Because the index of 18 is a multiple of 2, which is even, in contrast to odd numbers, the operation produces two results: (218)−1 = \pm 2; the positive value is the principal root.
Make sure to understand that exponentiation is not commutative, which means that 218 ≠ 182, and also note that (218)-1 ≠ 2-18, the inverse and reciprocal of 218, respectively.
