In this problem, we're being asked to simplify the expression negative i being raised to the third power.
00:06
And then we need to make sure our final answer is written in standard form.
00:09
Well, in this case, we can almost treat this as if we were to take negative x and raise it to the third power.
00:14
This means i need to multiply negative i by negative i times negative i times negative i.
00:20
Well, what i'm going to do first is i'm going to multiply the coefficients.
00:23
And remember, if you don't see a number in front of the i, it's a 1.
00:26
So it's really negative 1 times negative 1 times negative 1.
00:30
Well, that's still just negative 1.
00:33
And then when we multiply i times i times i, that's going to give us i to the 3rd.
00:38
Again, our directions want us to have our final answer in standard form...
