Question

If i is raised to an even power, then it can not simplify to be


Answers: -1, 1, i

Answer 1

\[i^0=1\\i^1=i\\i^2=-1\\i^3=-i\\\quad~\vdots\]

Answer 2

so the answer is -1

Answer 3

@bmx4life no, do out more iterations if you need.
i^0=1
i^1=i
i^2=-1
i^3=-i
i^4=1
i^5=i
i^6=-1
i^7=-i
i^8=1

do you see the answer now?

Answer 4

i

Answer 5

correct! Good job :)

Answer 6

ok thanks

Answer 7

if \(i\) is raised to a multiple fo two it will equal \(-1\) or \(1\)
if \(i\) is raised to an multiple of four it will equal \(1\)
