A= (1-1/2010) x (1- 2/2010) x (1- 3/2010) x.... x( 1- 2011/2010) =?
tìm x:
a. x+10/10 + x+10/11 + x+10/12 x+10/13 x+10/14
b.x+4/2010 x+3/2010 x+2/2010 x+1/2010
Tìm x:
a) x+(x+1)+(x+2)+...+200+201=401
b) x+(x+1)+(x+2)+...+2009+2010=2010
Tìm số nguyên x thoả mãn:x+(x+1)+(x+2)+…+(x+2009)+(x+2010)=2010
Tìm x thỏa mãn: x + (x + 1) + (x + 2) + … + 2009 + 2010 = 2010 A.-2010 B.-2008 C.0 D.-2009
Tìm x
x+(x+1)+(x+2)+...+2009+2010=2010
Bài 1: Tìm x biết:
1/ x + (x + 1) + (x + 2) + (x + 3) +.....+ (x + 2006) + 2007 = 2007
2/ x + (x + 1) + (x + 2) +...+ 199 + 200 + 201 = 401
3/ x + (x + 1) + (x + 2) +....+ 2009 + 2010 = 2010
Bn nào nhanh mik tick nha!!!
x + ( x + 1 ) + ( x + 2 ) + ... + 2009 + 2010 = 2010
1/x(x+1) +1/(x+1)(x+2) + 1/(x+2)(x+3) - 1/x = 1/2010
tìm x thuộc N biết rằng
a] x+[x+1]+[x+2]+...+[x+2010]=2029099
b] 2+4+6+8...+2x=2010
