Question

i^4+i^3+i^2+i

Answer 1

1-i-1+i=0

Answer 2

medal plzzzzzzz

Answer 3

do you know what i*i is?

Answer 4

i is \( \sqrt{-1} \) and i*i = -1

Answer 5

ok let me tel u how

Answer 6

r u there?

Answer 7

complex numbeers have one real and one imaginary part ok u know that
if (a,b) is complex number than a is real and b is imaginary ok
(1,0) is complex number whose imaginary part is 0 it only has real part
(0,1) is complex number having only imaginary part
if u know complex number multiplication than it is easy to prove that i*i=-1
i represents imaginary number i=(0,1)
(a,b)*(c,d)=(ac-bd,ad+bc)
(0,1)*(0,1)=(0-1,0+0)
=(-1,0) (-1,0) is real
(0,1)(0,1)=-1
i*i=-1

Answer 8

mEDAAAAAAAAAAAAAAAAAL

Answer 9

WHY DO PEOPLE DON'T GIVE MEDALS

Answer 10

that;s no good i gave u prove and u are gone
