Question

Află valoarea expresiei matematice: E=1000-(5×6+7×4)-(6×7+7×8)-(3×5×10)-(2+6+2)×10+(4+5)×9
Va rog,imi trebuie pt maine! Dau coroana+5stele!

Answer 1

E=1000-(5×6+7×4)-(6×7+7×8)-(3×5×10)-(2+6+2)×10+(4+5)×9

E=1000-(30+28)-(42+56)-(15×10)- (8+2)×10+9×9

E=1000- 58- 98- 150- 10×10+ 81

E= 942- 98- 150- 100+ 81

E= 844- 150- 100+ 81

E= 694- 100+ 81

E= 594+ 81

E = 675
