Explicație pas cu pas:

1. a) 4+(-12):3=

4-4=0

b) (-2)×(-5)-11=

10-11=-1

c)(-2)³-(-3)²=

-8-9=-17

2. a) (-7)×[(-3)³:9-]=

(-7)×(3³:3²-5)=

(-7)×(-3-5)=

(-7)×(-8)=

=56

b)(-24):(-2)³-9²=

(-24):(-2)³-81=

24/2³ -81=

24/8 -81=

3-81=-78

c) [(-5)×(-5)²+(-5)⁰]:4=

[(-5)³+1]:4=

(-125+1):4=

-124:4=-31
