, then the principal value of arg

\left(z^{2 / 3}\right)

is equal to

View answer and explanation

Correct option: B

\frac{2 \pi}{3}

2 \pi

\frac{10 \pi}{3}

Option B (

\frac{2 \pi}{3}

2 \pi

\frac{10 \pi}{3}

) is correct because it represents the possible values of the argument of

z^{2/3}

when

z=-1
