Let A,B,C be three cardinals. Show that...(adsbygoogle = window.adsbygoogle || []).push({});

[tex]A^{B+C} = A^B A^C[/tex]

I thought about using some some of distinguishing scheme where we denoted [tex]B \cup C[/tex] as [tex]B \times \{0\} \cup C \times \{1\}[/tex] so we could map thing easily but apparently that's not right and you can assume they are disjoint anyway...

EDIT: I just noticed the sticky at the top, this was just something in the notes we had that wasn't proven, not an assignment question or anything and I wanted to know how to do it. Should I repost this in another section?
