Sorry for the confusion

no problem hang on a sec kk?

TBMonkeyBest ResponseYou've already chosen the best response.0
the first one should be i*4.84 the second should be i*1.96

How did you figure those out?
 one year ago

Mathhelp346Best ResponseYou've already chosen the best response.0
I checked the answers at the back of my textbook and it says 42i√5. Is that the same thing?
 one year ago

TBMonkeyBest ResponseYou've already chosen the best response.0
yes but more complicated(:
 one year ago

Mathhelp346Best ResponseYou've already chosen the best response.0
Oh, ok. But how did you get those answers anyways?

step by step lol your book should tell you

It doesn't have an example on this type. I don't know how to solve it with a square root.
 one year ago

Mathhelp346Best ResponseYou've already chosen the best response.0
Can you show me how you solved it step by step?

only cuz of your adorable pikachus though :D

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

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

anikayBest ResponseYou've already chosen the best response.1
is that the problem in your book?
 one year ago

Mathhelp346Best ResponseYou've already chosen the best response.0
\[(1+i \sqrt{5})^{2}\]
 one year ago

anikayBest ResponseYou've already chosen the best response.1
so we square everything inside the parentheses. to get 4
 one year ago

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

anikayBest ResponseYou've already chosen the best response.1
so the answer should be 4.....imo
 one year ago

anikayBest ResponseYou've already chosen the best response.1
is there something about the problem I'm missing?
 one year ago

Mathhelp346Best ResponseYou've already chosen the best response.0
But the answers in my textbook say it's 42i√5. Or is your answer and the textbook's the same thing?
 one year ago

anikayBest ResponseYou've already chosen the best response.1
mine is simplifying the expression..... is that what your book is asking for
 one year ago

Mathhelp346Best ResponseYou've already chosen the best response.0
The textbook says multiply

*facepalm* I'm tired. gonna head to bed after I finish helping you
 one year ago

anikayBest ResponseYou've already chosen the best response.1
\[(1+i \sqrt{5})(1+i \sqrt{5})\]
 one year ago

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

anikayBest ResponseYou've already chosen the best response.1
so first we multiply 1 by 1
 one year ago

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

anikayBest ResponseYou've already chosen the best response.1
then we do the same thing again for the inside terms
 one year ago

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

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

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