do you know what \[i^2 \] is?
 2 years ago

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

Mathhelp346 Group TitleBest ResponseYou've already chosen the best response.0
That's it?

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

It's that

anikay Group TitleBest ResponseYou've already chosen the best response.1
so we square everything inside the parentheses. to get 4
 2 years ago

anikay Group TitleBest ResponseYou've already chosen the best response.1
because 1^2 = 1 and i^2 = 1 and sqrt(5)^2 = 5 right?
 2 years ago

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

1+i√5^2?
 2 years ago

anikay Group TitleBest ResponseYou've already chosen the best response.1
ok, F.O.I.L. Front, Outside, Inside, Last
 2 years ago

anikay Group TitleBest ResponseYou've already chosen the best response.1
so first we multiply 1 by 1
 2 years ago

anikay Group TitleBest ResponseYou've already chosen the best response.1
ok we get 1 next we mutiply \[1*i \sqrt{5}\]
 2 years ago

anikay Group TitleBest ResponseYou've already chosen the best response.1
then we do the same thing again for the inside terms
 2 years ago

anikay Group TitleBest ResponseYou've already chosen the best response.1
then the last, which is \[i \sqrt{5}*i \sqrt{5}\]
 2 years ago

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

Mathhelp346 Group TitleBest ResponseYou've already chosen the best response.0
oh ok thank you
