Hi guys, I know I'm a bit late to answer to this post, but we haven't still turned in the homework, so I'm still in time .

What I'd like to discuss, is that, if we are able to use the square root and the logarithmic function then we are able to express every single power of 2, For example:

But it is not all that useful. For example, I have implemented it only on 6, 10, 12, 16, 20.

In reality, I didn't quite like using the square root on a 4 by itself: it seemed like cheating, so I had to get inventive. For example 10 =

Or, 12 =

And so on.
