How to write a correct formula in Java?

Question

Java

Hello. There is a mathematical formula: Tell me

how to write it correctly, since my version is:
double paymentsCount = Math.log (1 / 1 - Im * 100 / Ap)/Math.log(1+Im)
throws an exception, despite the fact that the input data correct.

Answer 1

double paymentsCount = Math.log(1 / (1 - Im * 100 / Ap))/Math.log(1+Im)

Answer 2

Isn't it better to simplify and not to lose accuracy once again to replace with
- Math.log(1 - Im * 100 / Ap) / Math.log(1 + Im)
