I am stuck trying to solve for B this equation: \[\exp\left(\frac{B}{\sum_{i=1}^{n}x_{i}}\right)= \sum_{i=1}^{n}z_{i}\exp(Bz_{i})\] Last edited by Jaket1; November 4th, 2018 at 07:26 AM.

Thanks, I have used the link you shared. However, it is still not clear to me how I am supposed to approximate?
