    Logarithms in Exponents

    Okay I'm having a small issue with logarithms. I have this problem assigned by my teacher: Logarithms in Exponents-logstuff.gif. How precisely do I solve this problem? And moreover what is the general rule to solving other problems like this?

    Hello there,

    well i hope you know that you can simplify the exponential:
    e^{log_2 16} <br />
= e^{log_2 2^4}<br />
= e^{4log_2 2}<br />
= e^4

    actually you cannot solve the problem since there is no variable for which to solve

    it seems to simplify to e^4 + 2

    agreement?
