Me do this math problem. it is open ended with no answer choices to choose from, and i am sooo confused about how to do it. the attachment shows the problem.

Use Moivre Formula to find cube roots of 64(cos219+isin219)

Cubic roots =∛[64(cos219+isin219)] = [64(cos219+isin219)]^(1/3)

= 4[(cos219+isin219)]^(1/3)=4[cos(219)/3+isin219/3)]=
= 1.169 + 3.82 i

A. is the answer in this question
