e urgent!

Answer 1

Răspuns:

a. 29

b. -43

Explicație pas cu pas:

a. (-25):(-5)-3*{-2-3*[-8:(-2)-(-2)*(-1)]}=

=5-3*{-2-3*[4-2]}=

=5-3*{-2-3*2}=

=5-3*{-2-6}=

=5-3*-8=

=5-(-24)=

=29

b. (-25):(-5)-3*{-2-2*[(-12):2+3:(-1)]}=

=5-3*{-2-2*[-6-3]}=

=5-3*{-2-2*-9}=

=5-3*{-2-(-18)}=

=5-3*16=

=5-48=
