Multiplicative Inverse of 289

Multiplicative Inverse of 289 is defined as what you can multiply with 289 to get 1.
If the Multiplicative Inverse of 289 is x, the problem can be written as a function as follows:
289(x) = 1
Thus, to get the answer, we divide 1 by 289 like this:
1 / 289 = 0.00346021
Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.00346021 multiplied by 289 equals 1.
The Multiplicative Inverse of postive 289 has a positive answer and the Multiplicative Inverse of negative 289 has a negative answer. Therefore, the Multiplicative Inverse of -289 is -0.00346021.
