(4 + 2 i) (1 + 5 i)

Solution

- 6 + 22 i

Solution steps

(4 + 2 i) (1 + 5 i)

Apply complex arithmetic rule:

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

= (4 \cdot 1 - 2 \cdot 5) + (4 \cdot 5 + 2 \cdot 1) i

Simplify

(4 \cdot 1 - 2 \cdot 5) + (4 \cdot 5 + 2 \cdot 1) i : - 6 + 22 i

= - 6 + 22 i
