So what pattern do you see here? with i, i .i, i.
00:05
Squared, the third, i is the fourth.
00:06
I'm assuming that's what this is.
00:08
So i is just i.
00:12
I squared is the same as a square root of a negative one and that is a negative one.
00:23
I cubed would be the same as i squared of a negative one that squared as a negative one, type of negative one.
00:31
Well, we know these two would multiply the negative one and then you still have the squared of a negative one, so that would become negative i.
00:41
And then i to the fourth is four of the square roots of negative one, and that would be a negative one, and that would be a negative one, and negative one times negative one is one.

If we go even further, i to the fifth...
