Hello,

I'm working on a proof about Cantor Normal Form. In our notes we have that and as part of the proof I think I need to find a similar equation of the form

Can anyone suggest how I would find finish this equation?

Just to put it in perspective, this is the question I'm doing:

Let be a limit ordinal with Cantor Normal Form given by and . Prove that .

EDIT: sorry I should specify that , and are ordinals and is a positive integer.
