Question

stabiliti care dintre urmatoarele relatii sunt adevarate si care sunt false
a)[530+3×(95-5×15):12]-14×25=29
b)[(63+991×7):100+(37×111-56×37)×2]:11=37
c){[(40×20+50×16):200+72:8]:17-1}×[2+7×10-(30-5×6):2]=0

Answer 1

[530+3x(95-75):12]-350=29
(530+3x20:12)-350=29
(530+60:12)-350=29
(530+5)-350=29

[(63+6937):100+(4107-2072)x2]:11=
[(7000:100)+(2035x2)]:11=
(70+4070):11=
4140:11=376,36  fals

{[(800+800):200+9]:17-1}x[2+70-(30-30):2=
[(1600:200)+9]:17-1]x(2+70)=
[(8+9):17-1]x72=
17:17)-1]x72=
(1-1)x72=
0x72=0  adevarat


535-350=29  fals
