\[(b)\dfrac{\pi}{3}\]

\[(c)\dfrac{\pi}{2}\]

\[(d)\dfrac{2\pi}{3}\]

TopNewest\(z=\dfrac{(2 cis (\frac{\pi}{6}))^{4n+1}}{(2 cis (-\frac{\pi}{3}))^{4n}}\)

\(z=\left(\dfrac{2 cis (\frac{\pi}{6})}{2 cis (-\frac{\pi}{3})}\right)^{4n} 2 cis (\frac{\pi}{6})\)

\(z=2(cis (\frac{\pi}{2}))^{4n} cis (\frac{\pi}{6})\)

\(z=2(i)^{4n} cis (\frac{\pi}{6})\)

\(z=2 cis (\frac{\pi}{6})\)

\(\arg z = \boxed{\dfrac{\pi}{6}}\)
