Question

Escreva o valor de cada expressão a seguir.
b) (9+2).(-4).(5 -8)=
c) (-4 -1). 5 -2. (-2).(-1)=
d) -12+2.[(5 -2.3)+4].[-2.2.(-3)]=
e) 9-[-8 +(2.2+1)].5.(-1)+6=
f) (2 +1).(2 -6).{13+[-4+(-2.3+1)]}=

Answer 1

b)11*(-4)*(-3)= 132
c)(-5)*5-2*(-2)*(-1)= -29
d)-12+2*[(5 -2*3)+4]*[-2*2*(-3)]=> -12+2*[(5-6)+4]*12 => -12+24*[-1+4] => -12+24*3 => 60
e)9-[-8+(2*2+1)]*5*(-1)+6=>9-(-8+5)*(-5)+6=>9-(-3)*(-5)+6=>9-15+6= 0
f)3*(-4)*{13+[-4+(-5)]}=>-12*(13-9)=>-12*4=> -48
