what is i^4

OpenStudy (anonymous):

i^1 = 1

OpenStudy (anonymous):

i= sqrt(-1)

OpenStudy (anonymous):

OBVIOUSLY

OpenStudy (anonymous):

@love_jessika15 I think is trolling

OpenStudy (anonymous):

i is one zero of x^2+1

OpenStudy (dannyrod2000):

so what would it be?

OpenStudy (anonymous):

i^1 is just like saying what is 3^1 or 2^1

OpenStudy (anonymous):

what do you think the answer is? when something is raised to the first power what is the answer?

OpenStudy (dannyrod2000):

i edited the question, i messed up

OpenStudy (anonymous):

Oh Ok. so now you want to write it out to make it clearer i * i * i * i

OpenStudy (anonymous):

\[\sqrt{-1}\sqrt{-1}\sqrt{-1}\sqrt{-1}\]

OpenStudy (anonymous):

i^2 =-1 i^4=+1

OpenStudy (anonymous):

\[(\sqrt{-1\sqrt{-1}})(\sqrt{-1}\sqrt{-1})\]

OpenStudy (dannyrod2000):

what about i^5?

OpenStudy (anonymous):

add one more i to the list

OpenStudy (anonymous):

or I should say multiply one more i to the list

OpenStudy (anonymous):

i^5=i^4 * i1*i=i

OpenStudy (dannyrod2000):

so it is ?

OpenStudy (dannyrod2000):

@matricked

OpenStudy (anonymous):

yup
