Answer 1

3,2×{2,7×3,5+2×[5-0,1×(2+1:0,5)]}=
=3,2×{9,45+2×[5-0,1×(2+2)]}=
=3,2×[9,45+2×(5-0,1×4)]=
=3,2×[9,45+2×(5-0,4)]=
=3,2×(9,45+2×4,6)=
=3,2×(9,45+9,2)=
=3,2×18,65=
=59,68

Answer 2

3,2×{2,7×3,5+2×[5-0,1×(2+1:0,5)]}=
3,2×{9,45+2×[5-0,1×(2+2)]}=
3,2×[9,45+2×(5-0,1×4)]=
3,2×[9,45+2×(5-0,4)]=
3,2×(9,45+2×4,6)=
3,2×(9,45+9,2)=
3,2×18,65=
59,68

si raspunsul final este 59,68
