-ii

Explanation:

Recall that

i^2=-1i2=1

i^3=-ii3=i

i^4=1i4=1 (Any multiple of 44 exponent will also be 11)

With this in mind, we can rewrite i^59i59, since the exponent is a prime number.

i^59=color(blue)(i^56)*i^3i59=i56i3

Since 5656 is a multiple of 44, i^56=1i56=1. What we have simplifies to:

1*i^3=-i1i3=i

Hope this helps!

i^59=i^59xxi^2/i^2={(i^60)(i)}/(-1)=(i^4)^15*i/-1=1^15*-i=-ii59=i59×i2i2=(i60)(i)1=(i4)15i1=115i=i.
