exponents

if a^b^c^d, then do i calculate c^d part first, or the a^b part first?

Evaluate c^d first.


a^(b^(c^d)) is what this really means.

It's definitional. In general, parentheses should be used unless something tells you the order to use. Binding to the right is the only really sensible way, though, so I would suggest a^(b^(c^d)): the other way reduces to a tower of fixed hight regardless of the number of exponents.
