SUMMARY
The discussion centers on calculating the real part of the expression Re(α + α² + α³ + α⁴ + α⁵), where α = e^(i8π/11). The user successfully simplifies the expression to α(α⁵ - 1) / (α - 1). The suggestion to utilize Euler's formula, e^(ix) = cos(x) + i sin(x), is presented as a method to further simplify and solve the problem. This approach is essential for extracting the real component of the complex expression.
