Problem resolved to equation but how do I proceed?

  1. Feb 21, 2009 #1
    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!

    I doubt there is any way to do that algebraically.
