Question

calculeaza 825:(72:9-24:8)-(27×2:9×17)= si 6×5[54+7×(474:6-15×5)] = si 45+6×{48:8+3×[98-3×(25:5-70×0)]}= si 100 000-{100 000-(100 000-(351×7+192×9-518)×4+1979]}=

Answer 1

1) 825:(8-3)-102=825:5-102=165-102=63
2) 30[54+7×(79-75)]=30(54+7×4)=
=30×82=2460
3) 45+6×{6+3×[98-3×(5-0)]}=45+6×[6+3×(98-15)]=45+6×(6+3×83)=45+6×255=45+1530=1575
4) 100 000-{100 000-[100 000-(2457+1728-518)×4+1979]}=100 000-[100 000-(100 000-3667×4+1979)]=100 000-(100 000-87311)=100 000-12689=87311
