Question

(1+1/2+1/3+...+1/2008).X=2009/1+2010/2+2011/3+...+5016/2008-2008)

giúp mình vs mình đag cần gấp

Answer 1

\(\frac{2009}{1}+\frac{2010}{2}+...+\frac{5016}{2008-2008}\)

\(=\frac{2009}{1}+\frac{2010}{2}+...+\frac{5016}{0}\)

Sau đó QĐM(bạn tự QĐ nha)

\(=\frac{0}{0}+\frac{0}{0}+...+\frac{5016}{0}\)

\(=\frac{5016}{0}=0\)

\(\Rightarrow\left(1+\frac{1}{2}+\frac{1}{3}+...+\frac{1}{2008}\right).x=0\)

Mà \(\left(1+\frac{1}{2}+\frac{1}{3}+...+\frac{1}{2008}\right)\ne0\)

\(\Rightarrow x=0\)
