[(-2).(-1)]-3.-4)​

Answer 1

Respuesta:

[3.(-4)-(2.-3)].[(-8)+(-4)] / [(-2).(-1)].[-3.-4]

= [3.(-4)-(2.-3)].[(-8)+(-4)] / [(-2).(-1)].[-3.-4]

= [3.(-4)-(-6)].[(-8)+(-4)] / [(-2).(-1)].[-3.-4]

= [-12-(-6)].[(-8)+(-4)] / [(-2).(-1)].[-3.-4]

= [-12 + 6].[(-8)+(-4)] / [(-2).(-1)].[-3.-4]

= [-6].[(-8)+(-4)] / [(-2).(-1)].[-3.-4]

= [-6].[-12] / [2].[-3.-4]

= [-6].[-12] / [2].[12]

= 72 / [2].[12]

= 72 / 24

= 3

[(-2).(-1)]-3.-4)

= [2]-3.-4)

= [2]12)

= 24
