va rog este urgent dau 50 de puncte si coroana


Răspuns :

5 x [ (0 : 85 + 85 : 85) + 987 : 7 - 142] + 85 x 11 =
= 5 x [(0 + 1) + 987 : 7 - 142] + 85 × 11 =
= 5 x ( 1+ 141 - 142) + 85 x 11=
= 5 x 0 + 85 x 11 =
= 5 x 0 + 935 =
= 0 + 935 =
= 935

9 + 10 x [365 + 10 x (60 + 60 : 5) : 5 =
= 9 + 10 x [365 + 10 x (60 + 12)] : 5 =
= 9 + 10 x (365 + 10 x 72) : 5 =
= 9 + 10 x (365 + 720) : 5 =
= 9 + 10 x 1085 : 5 =
= 9 + 10850 : 5 =
= 9 + 2170 =
= 2179
1) = 5(0+1+ 141-142) + 935 = 5x0 +935=935
2) = 9 + 2(365 + 10(60+12)) = 9 + 2(365+720) = 9 + 2x1085 = 9+2170=2179
