a) 16 . (–2) =
b) (–3) . (–1) =
c) (–4) . 5 =
d) –(2 . 6) =
4) Dê o resultado de cada multiplicação:
a) (–8) . (+10) . (–2) =
b) (–7) . (–9) . (–3) =
c) (–10) . (–2) . (+5) . (+7) . (–4) =

Answer 1

Resposta:

a) 16 . (–2) =  -32

   $-32^{2} = 1024$

b) (–3) . (–1) =  3

  $3^{2} = 9$

c) (–4) . 5 =  -20

  $-20^{2} = 400$

d) –(2 . 6) =  -12

    $-12^{2} = 144$

4)

a) (–8) . (+10) . (–2) =   160

b) (–7) . (–9) . (–3) =  -189

c) (–10) . (–2) . (+5) . (+7) . (–4) = -2800

Answer 2

Resposta:

a) 16 . (–2) =  -32

  

b) (–3) . (–1) =  3

 

c) (–4) . 5 =  -20

 

d) –(2 . 6) =  -12

   

4)

a) (–8) . (+10) . (–2) =   160

b) (–7) . (–9) . (–3) =  -189

c) (–10) . (–2) . (+5) . (+7) . (–4) = -2800
