Answer 1

Răspuns:

200-(42-36) × 15

200-(42-36) × 15=200-6×15

200-(42-36) × 15=200-6×15=200-90

200-(42-36) × 15=200-6×15=200-90=110

6)[5×(28:7+9)-7×8]×4

=[5×(4+9)-7×8]×4

=[5×13-7×8]×4

=(65-56)×4

=9×4

=36

7) 24+{15:3+[16:(10-54:9)×3] }

=24+{15:3+[16:(10-6)×3] }

=24+{15:3+[16:4×3] }

=24+[15:3+(16:4×3) ]

=24+[15:3+(4×3) ]

=24+[15:3+12]

=24+(5+12)

=24+17

=41

8). 49:3+{240:[65-(32:8+6×9)+1 ] }

=49:3+ {240:[65-(4+54)+1]}

=49:3+{240:[65-58+1]}

=49:3+[240:(10+1)]

=49:3+[240:11]

=49:3+(240:11)

=49:3+240:11

=16,3 + 21,81

=38,11

9). ultimul nu pot
