Hi Nasser,

LogLogPlot sets up axes as log base 10. I don't know where you've
learned that it's base e, but it's not true.

However, If you are going to plot additional graphics, e.g. by using
Epilog, you will notice that those coordinates have to be log base e
to arrive at the desired location. For example:

LogLogPlot[x, {x, .1, 1}, Epilog -> Point[{Log[E, 0.5], Log[E, 0.5]}]]

Cheers -- Sjoerd
