Easy Problem

  1. May 5, 2005 #1
    Wow, I can't believe I couldn't do this.

    [tex]4^x=8x[/tex]

    I tried taking the natural logarithm of both sides, but that didn't help very much. I can see that an answer is 2, but I want to know how to get to that algebraicly.

    It has 2 real solutions which can be found graphically.The equation is transcendental.

    The solutions are expressible in terms of the Lambert function
