I am playing around with some image processing code, and I got stuck on a math problem. Since I am really not that good in math, I can't seem to be able to solve it. The issue is as follows:

a^n + b^n + c^n = d

a, b, c and d are all values larger than 0 but less than 1. I need to find n.

a^n + b^n + c^n = d

a, b, c and d are all values larger than 0 but less than 1. I need to find n.

Thanks.
