Multiplicative Inverse of 81

Multiplicative Inverse of 81 is defined as what you can multiply with 81 to get 1.
If the Multiplicative Inverse of 81 is x, the problem can be written as a function as follows:
81(x) = 1
Thus, to get the answer, we divide 1 by 81 like this:
1 / 81 = 0.01234568
Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.01234568 multiplied by 81 equals 1.
The Multiplicative Inverse of postive 81 has a positive answer and the Multiplicative Inverse of negative 81 has a negative answer. Therefore, the Multiplicative Inverse of -81 is -0.01234568.
