Homework Help: Set Theory Question

  1. Apr 22, 2012 #1
    Let D be a set that has cardinality d WTS that D has 2[itex]^{d}[/itex] subsets of cardinal number d.

    So I was thinking about slitting D into two sets C[itex]_{1}[/itex] and C[itex]_{2}[/itex] both of cardinality d. From there I think that there are d[itex]^{d}[/itex] subsets that contain C[itex]_{1}[/itex]. Since d is an infinite cardinal d[itex]^{d}[/itex]=2[itex]^{d}[/itex].

    Does that work or am I missing something>

    I have no idea what your question is. What does 'WTS' mean? And what are you trying to do?
