Did you know that there is a complex number whose cube is 8? Most people forget about complex numbers as a cube root. If someone asks, "What is the cube root of 8 ?", the majority of people will say 2. But -1 + sqrt(-3) is also the cube root of 8.

Let's verify by cubing -1+sqrt(-3)

(-1 + sqrt(-3))^3 = 1(-1)^3 + 3(-1)^2(sqrt(-3)) + 3(-1)(sqrt(-3)^2) + (sqrt(-3))^3

= -1 + 3(3i) - 3(3i)^2 + 3i^2(3i)

= -1 + 3(3i) + 9 -3(3i)

= 8

So if someone wants to wear #8 on a uniform, they could also be clever and say, "I want to wear number (-1 + sqrt(-3))^3."
