Find the complex number `omega` satisfying the equation `z^3=8i` and lying in the second quadrant on the complex plane.

Explanation

To find the complex number \( \omega \) satisfying the equation \( z^3 = 8i \) and lying in the second quadrant, we can follow these steps:

### Step 1: Rewrite the equation
We start with the equation:
\[ z^3 = 8i \]
We can express \( 8i \) in polar form. The modulus of \( 8i \) is \( 8 \) and the argument (angle) is \( \frac{\pi}{2} \) (since it lies on the positive imaginary axis).
