Question

nothing

Answer 1

do you know what \(\bf i^2\) is?

Answer 2

-1 right?

Answer 3

A lot of people want to answer this one.

Answer 4

heheh

Answer 5

well... . if you divide 38 by 2 you'd get 19... that means, there are 19 \(\bf i^2\) in there, so 19 minus 1, so what do you think is the value?

Answer 6

take the integer remainder when you divide by 4
the pattern is
\[i^0=1\\
i^1=i\\
i^2=-1\\
i^3--i\\
i^4=1\] so if the remainder is 3 for example you get \(-i\_

Answer 7

yea I was right its -1

Answer 8

yes, you were right, because the remainder is 2 when you divide 38 by 4

Answer 9
