Answer 1

Resposta:

Espero ter ajudado!

Explicação passo-a-passo:

a)16+[10-(6+2)+5]=

  16+[10-8+5]=

 16+7=23

b)25-[12-(6+1)]=

 25-[12-7]=

 25-5=20

c)90-[25+(10-1)+3]=

   90-[25+9+3]=

  90-37=53

..................................................

a)1000-[(8-6)+(2+24)]=

  1000-[2+26]=

 1000-28=972

b)60+2.{[4.8-10]+12}=

 60+2.{[32-10]+12}=

 60+2.{22+12}=

  60+2.34=

  60+68=128

c)[(4+32).5-10].100=

 [36.5-10].100=

  [180-10].100=

  170.100=17000
