Best ResponseYou've already chosen the best response.1Start with the first two \[(\sqrt{2}i)*(\sqrt{2}i)\]Using FOIL multiply your terms F  first terms O  outer terms I  inner terms L  last terms Once you have done that you add the next \[(\sqrt{2}i)\] and do it it all over, add your fourth \[(\sqrt{2}i)\]and do it again, combine terms and you have your answer.
