Question

calcule
a)(2+3i) + (-6+i)
b)(-4+4i) + (3-2i)
c)(-1-2i) - (-2+i)
d(8+i)-(3-5i)
e)(2+3i).(2+2i)​

Answer 1

Resposta:

Explicação passo-a-passo:

a.

2+3i-6+i=

-4+4i

b.

-4+4i+3-2i=

-1+2i

c.

-1-2i-(-2+i)=

-1-2i+2-i=

1-3i

d.

8+i-3+5i=

5+6i

e.

(2+3i).(2+2i)=

4+4i+6i+6i²=

4+10i+6.(-1)=

4+10i-6=

-2+10i
