Answer 1

To find the imaginary part of the complex number \( 4 - 2 \sqrt{3} - i \), we first simplify the expression.

The given expression is: \[ 4 - 2 \sqrt{3} - i \]

This can be rewritten as: \[ (4 - 2 \sqrt{3}) + (-1)i \]

From this form, you can see that the real part is \( 4 - 2\sqrt{3} \) and the imaginary part is \(-1\).

So, the imaginary part of the simplest form of the complex number is: \[ -1i \]

Thus, the correct response is:

-1i
