### 8 Puzzle

Another great puzzle I picked up at SIGGRAPH.

Consider the following set of symbols:

By adding these symbols in various combinations, each of the numbers 720 through 729 can be transformed into an expression yielding 8.

For example, the answer to 720 is:

7 + 2^0 = 8

The answers to 721, 722, 723, 724, 725, 726, 727, 728, 729 are left to you.

Some are easy. Some are pretty challenging.

Enjoy!

(Note to those less familiar with certain notation: The circumflex symbol indicates powers; i.e., x^2 = x to the power of 2 = x*x)
