Solution

simplify

(2 - 2 i) \cdot (4 - 4 i)

Solution

- 16 i

Solution steps

(2 - 2 i) (4 - 4 i)

Apply complex arithmetic rule:

(a + bi) (c + d i) = (a c - b d) + (a d + b c) i

= (2 \cdot 4 - (- 2) (- 4)) + (2 (- 4) - 2 \cdot 4) i

Simplify

(2 \cdot 4 - (- 2) (- 4)) + (2 (- 4) - 2 \cdot 4) i : - 16 i

= - 16 i
