Hello,

Urgently need some help with some Mathematical Communication.

The question is:

Show that the set of all odd square numbers {1,9,25,49,...} has cardinality ℵ0 [aleph-zero].

Any ideas? (Worried)

What is the largest cardinality, because surely I can start with the cardinality of the set of all Real numbers and then work from there?
