ex 7 va rooog dau coroana și 35 de puncte

Answer 1

50 + 4 × { 12 + 2 × [ 300 - 6 × ( 45- 3×7 + 2^3 )]} =
50 + 4 × { 12 + 2 × [ 300 - 6 × ( 45 - 21 + 8 ) ]} = 50 +4 × {12 + 2 × [300 -6 × (24 + 8 )]}=
50 + 4 × [12 + 2 × (300 -6 × 32 )]=
50 + 4 × [12 + 2 × (300 -192 )]=
50 + 4 × (12 + 2 × 108 )=
50 + 4 × (12 + 216 )=
50 + 4 × 228 =
50 + 912 =
962

Answer 2

50+4×{12+2×[300-6×(45-3×7+2^3)]}=
50+4×{12+2×[300-6×(45-21+8)]}=
50+4×{12+2×[300-6×(24+8)]}=
50+4×[12+2×(300-6×32)]=
50+4×[12+2×(300-192)]=
50+4×(12+2×108)=
50+4×(12+216)=
50+4×228=
50+912=962
