(8³ ₓ 8⁴) / (8²)⁴      for the first set of exponents, we add them
                           when you raise an exponent to an exponent..multiply
8⁷ / 8⁸                any exponent on the bottom changes signs when it moves

8⁷ ₓ 8⁻⁸              we move the 8⁸ from the bottom to the top and change signs

8⁻¹                now we just subtract or add
