tim x biet (2x+1)+(2x+2)+...+(2x+2015)
tim x biet (2x+1)+(2x+2)+...+(2x+2015)=0
tim x biet (2x+1)+(2x+2)+...+(2x+2015)=0
tim x biết (2x+1).(2+2)+...+(2x+2015)=0
giai giup em nha
tim x biet (2x+1)+ (2x+2)...+(2x+2015)=0
tìm x
Tim x la so tu nhien, biet:
x - 4/2015 - 1/2015 = 10 - 2x
Tim GTNN
1) A= |X| + 7
2) C= x2 - 23
3) D= (2x + 4)2 +2015
4) E= |2x - 100| + (y+8)2 - 1
tìm x biết (2x +1)+(2x +2)+...+(2x + 2015).x=
Tìm x : (2x + 1) + (2x + 2) + (2x + 3) + ... + (2x + 2015) = 0
