Question

Se v = ( 4 + 2i ) e w = ( 3 + 5i ). Qual o valor do produto v . w ?​

Answer 1

Resposta:

$\boxed{\boxed{\underbrace{V\times W=( 2 + 26i )}}}$

Explicação passo-a-passo:

$v = ( 4 + 2i ) \\ w = ( 3 + 5i )\\V\times W=( 4 + 2i ) ( 3 + 5i )\\V\times W=( 12 + 20i +6i +10i^2 )\\V\times W=( 12 + 26i +10(-1 ))\\\boxed{\boxed{\underbrace{V\times W=( 2 + 26i )}}}$
