1/2 x 1/1^2 x 1/1^3 x 1/1^4 x ... x 1/1^2012
- Ai nhanh mình tick cho nhé . Camon cacau nl <4
(1 + x) + (2 + x) + ( 3 + x) + ... +(10 + x) = 75
- Ai nhanh mình tick chó nhé <4 Nhanh lên nào >< Mk đag cần nhes <3
tìm x
a ,x-7/4+x-6/3+x-5/3+x+81/7=0
b,x-1/2013+x-2/2012+x+3/2011+...+x-2012/2=2012
c(1/1x101=1/2x102+1/3x103+1/4x164+1/10x110)x X =(1/1x11+1/2x12+...+1/100x110)
ai nhanh mình tick
Tìm x:
x . (1/2+1/3+1/4+. . .+1/2011+1/2012)
2012/1+2011/2+2010/3+2009/4+ . . . +2/2011+1/2012
=1
Tim x:
x . (1/2+1/3+1/4+. . .+1/2011+1/2012)
2012/1 +2011/2+2010/3+2009/4+2/2011+1/2012
=1
Tìm x
a, x+1/2 + x+2/3 + x+3/4 + x+4/5 + ....+ x+5/6=5
b, x+1/2017 + x+2/2016 + x+3/2015 = x+4/2014 + x+5/2013 + x+6/2012
(1/2+1/3+1/4+...+1/2013).x=2012/1+2011/2+...+2/2011+1/2012
bài 3 : TÌm x biết.
3^2 - 1/2.| 3/2.x +3 | = 2^2 . (1/4 - 3/2 ) - 2012^0
