Which form is more simplified? log_2 x^2 or 2log_2 x?

Well it's debatable however I would go with 2log_2 x.
It also depends on what the question is asking you to do

There's the 100th post too! :D ha

Actually, I wouldn't write anyway, it's

That's because the x^2 one allows negative values of x :P
Or just leave it at that

Yeah I know that haha, I just don't know how to type it with the modulus!
Let me off this time?

When sketching the exponential and log graphs, we do need to use the 3 points or just simply find the asymptote and x,y intercepts if any?

You should find the asymptote and any axis intercepts

Our teacher said that, if there's only one intercept, then put two scale points in, and if there's two intercepts, then just one
That may seem a bit excessive, but he is an examiner :P
