Are these two different questions? Is ᵋ the universal set, and is A' the complement of A?
What have you tried and what are your difficulties? Do you understand all the concepts involved?
Yes. They're two different questions. I did the first one though. I don't understand the second one. I think we can assume that ᵋ is just a set that includes 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and that A' is the complement of A.
Also, for the first one, correct me if I'm wrong. I came to the conclusion that basically the elements that could be in there were odd numbers, so I listed odd numbers.

My guess is that the second question asks to find the complement of {1, 4, 7, 9} when the whole (universal) set is {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}.
