Question

Va rog frumos imi trebuie lu
ni la sc ne note plang!! Problemele dupa poza 1,2 si trei va dau 25 de puncte si coroana!!

Answer 1

1. (5^2+15×6):5-2^2×5+3 =
(25+90):5-4×5+3 =
115 :5 -20+3 =
23-20+3 = 3+3 = 6

2. A (2+3)^2 =5^2 =25
B 2^2+3×2 = 4+3×2 = 4+6=10
C (2^2+3)×2 = (4+3)×2=7×2=14

3. 10+4×3^2-7×5-(3+2^3) =
10+4×9-35-(3+8) =
10+36-35-11 =
46-35-11 =
11-11= 0

2017-{[42-(5^2×14-85×4)×2]×3+2^6} =
2017 - {[42-(25×14-340)×2]×3+64} =
2017-[42-(350-340)×2]×3+64]=
2017-[42-10×2]×3+64] =
2017-(42-20)×3+64 =
2017-22×3+64 =
2017-66+64=
1951+64= 2015

(10^2-7^2+5^4)×(233^0+1^1500) =
(100-49+256)×(1+1) =
(51+625)×2=
676×2= 1342
