ME AJUDEM, QUESTÃO DE ENSINO FUNDAMENTAL

2) Operações com números complexos:

- Seja z= 3+i e w=3-i calcule:

a) z + w =
b) z - w =
c) w - z =
d) z .w =

Answer 1

a)z+w=
3+i+3-i=
3i-3i=
0i

b)z-w=
3+i-3-i=
3i+3i=
6i
c)w-z=
3-i-3+i=
3i+3i=
6i

d)z.w=
3+i.3-i=
3i/3i=
-0

Answer 2

a)z+w=        b)z-w=3+i+3-i=

3i-3i=

0i

b)z-w=

3+i-3-i=

3i+3i=

6i

c)w-z=

3-i-3+i=

3i+3i=

6i

d)z.w=

3+i.3-i=

3i/3i=-0-0
