Let the minimum value

v_0

v=|z|^2+|z-3|^2+\mid z-

\left.6 i\right|^2, \quad z \in \mathbb{C}

is attained at

z=z_0

. Then

\left|2 z_0^2-\bar{z}_0^3+3\right|^2+v_0^2

is equal to

View answer and explanation

Correct option: A

1000

Option A (1000) is correct because by finding the minimum value of v and the corresponding z_0, we can substitute these values into the given expression and evaluate it to 1000.
