1. This is originally a physical problem in semiconductors 2. Problem has been resolved to one equation with decimal powers 3. 1.6x^0.65 - 1.4x^0.2 = 0.2 By inspection, x could easily be 1 but that is not the solution as the value for x is less than 1. How can I resolve this equation further to obtain x without using numerical methods / graphical solution?? Thanks for your help!
