Welcome to **1 to the negative 81st power**, our post about the mathematical operation *exponentiation of 1 to the power of -81*.

If you have been looking for 1 to the negative eighty-first power, or if you have been wondering about 1 exponent minus 81, then you also have come to the right place.

The number 1 is called the base, and the number minus 81 is called the exponent. In this post we are going to answer the question *what is 1 to the negative 81st power*.

Keep reading to learn everything about one to the negative eighty-first power.

## What is 1 to the Negative 81st Power?

1 to the negative 81st power is conventionally written as 1^{-81}, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 1^-81.

1^{-81} stands for the mathematical operation *exponentiation of one by the power of negative eighty-one*.

As the exponent is a negative integer, exponentiation means the reciprocal of a repeated multiplication:

The absolute value of the exponent of the number -81, 81, denotes how many times to multiply the base (1), and the power’s minus sign stands for reciprocal.

Thus, we can answer what is 1 to the negative 81st power as

**1 to the power of minus 81 = 1**.

## 1 to the Power of -81

Reading all of the above, you already know most about 1 to the power of minus 81, 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, 1 to the power minus 81, and you will be taken to a result page with relevant posts.

Now, we would like to show you what the inverse operation of 1 to the negative 81st power, (1^{-81})^{−1}, is. The inverse is the 1 over the 81st root of 1^{81}, and the math goes as follows:

(1^{-81})^{−1}

= \frac{1}{\sqrt[81]{1^{81}}}

= \frac{1}{1^{81/81}}

= \frac{1}{1^{1}}

= \frac{1}{1}

Because the index of 81 is not a multiple of 2, which means odd, in contrast to even numbers, the operation produces only one value: (1^{81})^{−1} = \frac{1}{1}.

Make sure to understand that exponentiation is not commutative, which means that 1^{-81} ≠ -81^{1}, and also note that (1^{-81})^{-1} ≠ 1^{81}, the inverse and reciprocal of 1^{-81}, respectively.

You already know what 1 to the power of minus 81 equals, but you may also be interested in learning what 1 to the 81st power stands for.

Next is the summary of negative 81 power of 1.

## One to the Negative Eighty-first Power

You have reached the final part of one to the negative eighty-first power. One to the negative eighty-first power is the same as 1 to the power minus 81 or 1 to the minus 81 power.

Exponentiations like 1^{-81} make it easier to write multiplications and to conduct math operations as numbers get either big or small, such as in case of decimal fractions with lots of trailing zeroes.
