Question

if A={1,2,3,4} and B={2,4,6,8} then find A^B

Answer 1

I take it you mean
\[A \cap B\]?

Answer 2

hah think how it would be if the question reallyis A^B

Answer 3

I would never discount the possibility that I'm missing something :)

Answer 4

If that were the case, by the way, just take the set containing elements that are found in BOTH A and B. :)

Answer 5

From Mathematica:\[\text{Intersection}[\{1,2,3,4\},\{2,4,6,8\}]\to \{2,4\} \]\[\text{Union}[\{1,2,3,4\},\{2,4,6,8\}]\to \{1,2,3,4,6,8\} \]
