Question

what is the power on the sets in the image????

Answer 1

Did you mean to ask about C or ' on the sets?

Well then, it means compliment of the set.

I will explain you what is compliment with a simple example.

Let U = {1, 2, 3, 4, 5, 6, 7, 8}

And A = {1, 2, 3}

So, A' or A^c = {4, 5, 6, 7, 8}

In simple terms, the elements which are not in A are A compliment (represented by A' or A^c).
