Answer 1

Răspuns:

a) 234

b)2480

c)564

Explicație pas cu pas:

a)9+4×[30+2×(4+3×5)-11]-3=

=9+4×[30+2×(4+15)-11]-3=

=9+4×(30+2×19-11)-3=

=9+4×(30+38-11)-3=

9+4×(68-11)-3=

9+4×57-3=

9+228-3=

237-3=

234

b)[160+12×9-(15×2-50:5)]×10=

=[160+12×9-(30-10)]×10=

=(160+12×9-20)×10=

=(160+108-20)×10=

=(268-20)×10=

=248×10=

=2480

c)6+6×[6+3×(6+26×1-24:8)]=

=6+6×[6+3×(6+26-3)]=

=6+6×[6+3×(32-3)]=

=6+6×(6+3×29)=

=6+6×(6+87)=

=6+6×93=

=6+558=

=564
