We know that i=√-1
so we do pemdas
$\frac{1}{2} i$ = $\frac{ \sqrt{-1} }{2}$
exponents
$( \frac{ \sqrt{-1} }{2} )^{2}= \frac{( \sqrt{-1} )^{2}}{2^{2}}$ = $\frac{-1}{4}$
then $(-2i)^{2}$ =-2 times -2 times i times i=4 times -1=-4
now we have

$4i( \frac{-1}{4} )(-4)$ = $( \frac{-4i}{4} )(-4)$ = $( -i)(-4)$ =4i=aprox 4√-1

the answer is 4i
