I think you need to clarify what you are doing.

Small print is an obstacle.

Hmm, I can't type omega or power in your forum??

You can save them and zoom.

Or open in new tape and zoom.

What is your opinion?

As ω + ω² = -1, (1 - ω)(1 - ω²) = 1 - ω - ω² + ω³ = 2 + 1 = 3.
Similarly, each successive pair of factors has product 3.

But why you are taking successive pairs?

I think 2n means the number of our factors.

As there are 2n factors, there are n pairs of factors.

I used successive pairs of factors because each such pair has product 3.
