The big black numbers and letters at the bottom of the 3 parts are my answer to each part of the question. I'm getting the feeling like I did something wrong, but I can't figure out what I did wrong. May you please point of what I did wrong if you see anything?

E(82) = 19

E(22) - 8 = 11 - 8 = 3

[E(82)] ^ {E(22) - 8} = 19 ^ 3 = ?

I love your response to my question Subhotosh Khan. That cleared everything up to a whole new level. 19^3 = 6859 which is correct.
