## Integral Powers of Iota – Complex Numbers

Here you will learn complex number i (iota) and integral powers of iota with examples. Let’s begin – Integral Powers of Iota (i) Positive Integral Powers of iota(i) : We have, i = $$\sqrt{-1}$$ $$\therefore$$ $$i^2$$ = -1 $$i^3$$ = $$i^2$$ $$\times$$ i = -i $$i^4$$ = $$(i^2)^2$$ = $$(-1)^2$$ = 1 In order to …
