Definition 2. Let E(1) be denoted by the number e. Using the series e = E(1) = Eo, we can approrimate e to any degree of accuracy. In particular e 2.71828. In light of Property 6, we see that for any rational number r, E(r) = e". Not only does this give us the series representation e" = Eo r" for any rational number r, but it gives us a way to define e for irrational values of r as well. That is, we can define e = E(r) = for any real number z. As an illustration, we now have ev =E (V2)". The expression ev2 is meaningless if we try to interpret it as one irrational number raised to another. What does it mean to raise anything to the v2 power?
