    Now that you have seen some useful theory... What have you tried so far? You need to show some work before you will see a deluge of helpful hints on the forum. :wink:

    Yes sir, I did tried. But when I do...It coems to a point where I have to take inverse of log... and I dont think there is inverse function for log..
    Or is there? If yes how to do in calculator?
    Or am i on wrong way?
