Best ResponseYou've already chosen the best response.1do you know what \[i^2 \] is?

Best ResponseYou've already chosen the best response.1ok, so..... \[(1+i+\sqrt{5})^2\] that's it?

Best ResponseYou've already chosen the best response.1is that the problem in your book?

Best ResponseYou've already chosen the best response.0\[(1+i \sqrt{5})^{2}\]

Best ResponseYou've already chosen the best response.1so we square everything inside the parentheses. to get 4

anikay

Best ResponseYou've already chosen the best response.1because 1^2 = 1 and i^2 = 1 and sqrt(5)^2 = 5 right?

anikay

Best ResponseYou've already chosen the best response.1so the answer should be 4.....imo

Best ResponseYou've already chosen the best response.0But the answers in my textbook say it's 42i√5. Or is your answer and the textbook's the same thing?

Best ResponseYou've already chosen the best response.1ok, F.O.I.L. Front, Outside, Inside, Last

Best ResponseYou've already chosen the best response.1so first we multiply 1 by 1

anikay

Best ResponseYou've already chosen the best response.1ok we get 1 next we mutiply \[1*i \sqrt{5}\]

anikay

Best ResponseYou've already chosen the best response.1then we do the same thing again for the inside terms

anikay

Best ResponseYou've already chosen the best response.1then the last, which is \[i \sqrt{5}*i \sqrt{5}\]

anikay

Best ResponseYou've already chosen the best response.1so all together, we get\[1 i \sqrt{5}  i \sqrt{5}  5\] which simplifies to \[4 2i \sqrt{5}\]

Best ResponseYou've already chosen the best response.1so F.O.I.L, gotta remember that :P
