Given the sets C and D where...?

C = { {1}, 2}


D = {3, 4, 5}





list the contents of


1) D x C (multiply)


2) P(C), the power set of C

Given the sets C and D where...?
1) {3,{1}}, {4,{1}}, {5,{1}}, {3,2}, {4,2}, {5,2}





2) The power set, P(C), is the set of all the subsets of C.


There are two elements in C, so there will be 2^2 = 4 subsets.


P(C) = { {empty set}, {{1}}, {2}, {{1}, 2} }
Reply:That gave me a headache.
