Solution

simplify

(5 - 3 i) (2 + 4 i)

Solution

22 + 14 i

Solution steps

(5 - 3 i) (2 + 4 i)

Apply complex arithmetic rule:

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

= (5 \cdot 2 - (- 3) \cdot 4) + (5 \cdot 4 - 3 \cdot 2) i

Simplify

(5 \cdot 2 - (- 3) \cdot 4) + (5 \cdot 4 - 3 \cdot 2) i : 22 + 14 i

= 22 + 14 i
