Complex Multiplication is Commutative/Examples/(2 - 3i) (4 + 2i)

Examples of Use of Complex Multiplication is Commutative

Example: $\paren {2 - 3 i} \paren {4 + 2 i}$

$\paren {2 - 3 i} \paren {4 + 2 i} = 14 - 8 i$

Example: $\paren {4 + 2 i} \paren {2 - 3 i}$

$\paren {4 + 2 i} \paren {2 - 3 i} = 14 - 8 i$

As can be seen:

$\paren {2 - 3 i} \paren {4 + 2 i} = \paren {4 + 2 i} \paren {2 - 3 i}$

$\blacksquare$
