Resolva as expressões em Z:
a) 4 + 2 . 3 [-7 + (-8 : 4)] =


b) - 5 . { - 40 + [ - 30 : (-80 :16)]} =

Answer 1

Resposta:

Explicação passo-a-passo:

a) 4 + 2 . 3 [-7 + (-8 : 4)] =

4+6*[-7+(-2)]=

4+6*[-7-2]=

4+6*[-9]=

4+[-6*9]=

4+[-54]=

4-54= - 50

b) - 5 . { - 40 + [ - 30 : (-80 :16)]} =

-5 *{ -40+[-30:(-5)]}=

-5 *{-40+[+30:5]}=

-5*{-40+[+6]}=

-5*{-40+6}=

-5*{-34}=

+5*34= 170
