If you have been looking for 2 to the twentieth power, or if you have been wondering about 2 exponent 20, then you also have come to the right place. 🙂
The number 2 is called the base, and the number 20 is called the exponent. In this post we are going to answer the question what is 2 to the 20th power.
Keep reading to learn everything about two to the twentieth power.
What is 2 to the 20th Power?
2 to the 20th power is conventionally written as 220, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 2^20.
220 stands for the mathematical operation exponentiation of two by the power of twenty.
As the exponent is a positive integer, exponentiation means a repeated multiplication:
The exponent of the number 2, 20, also called index or power, denotes how many times to multiply the base (2).
Thus, we can answer what is 2 to the 20th power as

2 to the Power of 20
Reading all of the above, you already know most about 2 to the power of 20, 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 20, 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 20th power, (220)−1, is. The inverse is the 20th root of 220, and the math goes as follows:
Because the index of 20 is a multiple of 2, which is even, in contrast to odd numbers, the operation produces two results: (220)−1
; the positive value is the principal root.
Make sure to understand that exponentiation is not commutative, which means that 220 ≠ 202, and also note that (220)-1 ≠ 2-20, the inverse and reciprocal of 220, respectively.
