# Math Help - Cantor canonical form

1. ## Cantor canonical form

Find the Cantor canonical form of $\omega \cdot (\omega^{\omega}+1)+(\omega^{\omega}+1) \cdot \omega$.

Here the Cantor canonical form just means the Cantor normal form. I do not know how to find this form. I am stuck on this problem. I would appreciate some help. Thanks.

(In my opinion, the OP should have done this, or at least he/she should post a message like this after he gets a satisfactory answer in one of the forums.)
