  1. Again, having a hard time trying to establish the order of operation.
    e.g. #3
    I put it into Wolfram the way you typed it , and the webpage interpreted it the same way I did

    http://www.wolframalpha.com/input/?i=+X%5Elogx%2B5%2F3%3D+10%5E5%2Blog+x

    What a messy equation that would be to solve
    I have a feeling you meant something like

    X^logx + 5/3= 10^(5+log x)

    looks like very messy stuff for the other equations as well, the way you typed it.

    Prove that log a, log ar, log ar^2 is an a.p. Is the following below correct? Log ar^2 - Log ar= Log ar - Log a hence applying laws of logarithm Log(ar^2/ar) = log(ar/a) Log and log cancels out and then cross-multiply hence a^2r^2
