The principal argument of the complex number

\frac{(1+i)^5(1+\sqrt{3} i)^2}{-2 i(-\sqrt{3}+i)}

View answer and explanation

Correct option: C

-\frac{5 \pi}{12}

Option C (

-\frac{5 \pi}{12}

) is correct because calculating the argument of each complex number and using the properties of arguments leads to the principal argument being

-\frac{5 \pi}{12}
