Question

Resolva : (3- 2i)² + (2 - 3i)³ =

Answer 1

Resposta:

(3- 2i)² + (2 - 3i)³ =-41-21i

Explicação passo-a-passo:

(3- 2i)² + (2 - 3i)³ =

9-12i+4i²+(2-3i)(2-3i)²=

9-12i+4i²+(2-3i)(4-12i+9i²)=

9-12i-4+(2-3i)(4-12i-9)=

5-12i+(2-3i)(-5-12i)=

5-12i-10-24i+15i+36i²=

-5-36-21i

-41-21i

Obs: i²= -1
