Question

Vaa rooog 5,7,8 si daca puteti si 9

Answer 1

5)
10+9×{8+7×[6+5×(4+3×2)]}=
10+9×{8+7×[6+5×(4+6)]}=
10+9×[8+7×(6+5×10)]=
10+9×[8+7×(6+50)]=
10+9×(8+7×56)=
10+9×(8+392)=
10+9×400=
10+3600=
3610
7)
x∈(a,b) ,x∈N , x=?
a=6+8×[32:4-5×(4³-7×3²)]
a=6+8×[8-5×(64-7×9)]
a=6+8×[8-5×(64-63)]
a=6+8×(8-5×1)
a=6+8×(8-5)
a=6+8×3
a=6+24
a=30
b=15×2+(64:4+4):5+1313:13
b=30+(16+4):5+101
b=30+20:5+101
b=30+4+101
b=34+101
b=135
x∈(30,135)
x={31,32,33,34,....133,134}
