Question

80+{10+2x[-20-45:(13-2x5)]}=

Answer 1

Explicação passo-a-passo:

80+{10+2x[-20-45:(13-2x5)]}=

=80+{10+2.[-20-45÷(13-10)]}

=80+{10+2.[-20-45÷(3)]}

=80+{10+2.[-20-15]}

=80+{10+2.[-35]}

=80+{10-70}

=80+{-60}

=80-60

=20

Answer 2

80+{10+2x[-20-45:(13-2x5)]}=

80 + {10 + 2 × [- 20 - 45 : ( 13 - 10)]}

80 + {10 + 2 × [- 20 - 45 : 3 ]}

80 + {10 + 2 × [ - 20 - 15]}

80 + {10 + 2 × [ - 35]}

80 + {10 + [ - 70]}

80 + { 10 - 70}

80 + { - 60}

80 - 60

20
