By De Moivre's formula, the <em>cubic</em> roots of the <em>complex</em> number are 3 + i 4, - 4.96 + i 0.60 and 1.96 - i 4.60.
<h3>How to find the cube root of a complex number</h3>
Herein we have a <em>complex</em> number in <em>rectangular</em> form, from which we need its magnitude (r) and direction (θ) and the De Moivre's formula as well. The <em>root</em> formula is introduced below:
, for k ∈ {0, 1, ..., n - 1} (1)
Where n is the grade of the complex root.
The magnitude and direction of the <em>complex</em> number are 125 and 0.886π radians, respectively. Thus, by the De Moivre's formula we obtain the following three solutions:
k = 0
z₁ = 2.997 + i 4.002
k = 1
z₂ = - 4.964 + i 0.595
k = 2
z₃ = 1.967 - i 4.597
By De Moivre's formula, the <em>cubic</em> roots of the <em>complex</em> number are 3 + i 4, - 4.96 + i 0.60 and 1.96 - i 4.60.

For 9 you would want 2/3 of an 8” pizza because you get a higher amount of pizza
Answer:
Step-by-step explanation:
<u>Circumference formula:</u>
- C = 2πr,
- where π = 3.14, r - radius
1.
- C = 18.8 in
- 2*3.14r = 18.8
- 6.28r = 18.8
- r = 18.8/6.28
- r = 2.99 ≈ 3 in
2.
- C = 22 in
- 6.28r = 22
- r = 22/6.28
- r ≈ 3.5 in
