Find the fourth roots of 81(cos 320° + i sin 320° ). Write the answer in trigonometric form.
Liono4ka [1.6K]

Using the De Moivre's Theorem, let us work out for the fourth roots of 81(cos 320° + i sin 320° ).


zⁿ = rⁿ (cos nθ + i sin nθ) 
z⁴ = 81(cos 320° + i sin 320° ) 
z = ∜[81(cos 320° + i sin 320° )] 
= ∜[3^4 (cos 4*80° + i sin 4*80°)] 
= 3(cos 80° + i sin 80°)
