## What is 10 to the 90th Power?

10 to the 90th power is conventionally written as 1090, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 10^90.

1090 stands for the mathematical operation exponentiation of ten by the power of ninety.

As the exponent is a positive integer, exponentiation means a repeated multiplication:

10 to the 90th power = \underbrace{ {\rm 10 \times\thinspace ... \times\thinspace 10} }_{\rm 90 \thickspace times} The exponent of the number 10, 90, also called index or power, denotes how many times to multiply the base (10).

Thus, we can answer what is 10 to the 90th power as

## 10 to the Power of 90

Reading all of the above, you already know most about 10 to the power of 90, 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, 10 to the power 90, and you will be taken to a result page with relevant posts.

Now, we would like to show you what the inverse operation of 10 to the 90th power, (1090)−1, is. The inverse is the 90th root of 1090, and the math goes as follows:

(1090)−1
= \sqrt{10^{90}}
= 10^{90/90}
= 10^{1}
= 10

Because the index of 90 is a multiple of 2, which is even, in contrast to odd numbers, the operation produces two results: (1090)−1 = \pm 10; the positive value is the principal root.

Make sure to understand that exponentiation is not commutative, which means that 1090 ≠ 9010, and also note that (1090)-1 ≠ 10-90, the inverse and reciprocal of 1090, respectively.
