What is 1 to the Negative 90th Power?
1 to the negative 90th power is conventionally written as 1-90, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 1^-90.
1-90 stands for the mathematical operation exponentiation of one by the power of negative ninety.
As the exponent is a negative integer, exponentiation means the reciprocal of a repeated multiplication:
The absolute value of the exponent of the number -90, 90, 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 90th power as

1 to the Power of -90
Reading all of the above, you already know most about 1 to the power of minus 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, 1 to the power minus 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 1 to the negative 90th power, (1-90)−1, is. The inverse is the 1 over the 90th root of 190, and the math goes as follows:
Because the index -90 is a multiple of 2, which means even, in contrast to odd numbers, the operation produces two results: (1-90)−1 =
; the positive value is the principal root.
Make sure to understand that exponentiation is not commutative, which means that 1-90 ≠ -901, and also note that (1-90)-1 ≠ 190, the inverse and reciprocal of 1-90, respectively.
You already know what 1 to the power of minus 90 equals, but you may also be interested in learning what 1 to the 90th power stands for.
Next is the summary of negative 90 power of 1.
One to the Negative Ninetieth Power
You have reached the final part of one to the negative ninetieth power. One to the negative ninetieth power is the same as 1 to the power minus 90 or 1 to the minus 90 power.
Exponentiations like 1-90 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.
