Answer 2

Answer:

10/9 +  $\frac{1}{3} \sqrt{10}$ i

Step-by-step explanation:

($\frac{1}{3} \sqrt{5}$ - $\frac{1}{2} \sqrt{2}$i) ² =

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

5/9 + $\frac{1}{3} \sqrt{5}$ $\sqrt{2}$ i - (5/9. (-1)) =

10/9 +  $\frac{1}{3} \sqrt{10}$ i
