Answer 2

Geometrically - The Roots of unity are spread evenly round a circle
We write the Complex number in polar form :
1=1(Cos 0 + I sin 0)
Next use formul sqrtN = 1{( Cos (2pie*k/n) + i Sin( 2piek/n) }
Plug in n = 8 and k =3
AND you will get your values.. ..

Answer 3

\[=> \frac{ -\sqrt{2} }{ 2 } + \frac{ \sqrt{2} }{ 2 }\]

is your ans

Answer 4

seventh root of unity is \(cos (2\pi/7) +isin(2\pi/7)\)
