Simplify the complex numbers using de moivre's theorem and match them with their solutions.

For the numbers in form, convert to polar form:

By DeMoivre's theorem,

For the numbers already in polar form, DeMoivre's theorem can be applied directly:

At second glance, I think the 2s in the last two numbers should also be getting raised to the 3rd and 4th powers:

step-by-step explanation:

mean or average is 40.6
