\(\Leftrightarrow1-\frac{1}{2}+\frac{1}{2}-\frac{1}{3}+\frac{1}{3}-...+\frac{1}{8}-\frac{1}{9}+\frac{1}{9}-\frac{1}{10}\cdot x=\frac{22}{45}\)
\(\Rightarrow1-\frac{1}{10}.x=\frac{22}{45}\)
\(\Rightarrow\frac{9}{10}.x=\frac{22}{45}\)
\(\Rightarrow x=\frac{22}{45}:\frac{9}{10}\)
\(\Rightarrow x=\frac{22}{45}.\frac{10}{9}=\frac{22.10}{45.9}=\frac{44}{81}\)
=>x=\(\frac{44}{81}\)
tìm x biết:(1/1.2.3+2/2.3.4+...+1/8.9.10).x=22/45
Tìm số tự nhiên X, biết: ( 1/1.2.3 + 1/2.3.4 + ....+1/8.9.10) x X = 22/45
(1/1.2.3+1/2.3.4+...+1/8.9.10).x=22/45
(\(\dfrac{1}{1.2.3}\)+\(\dfrac{1}{2.3.4}\)+....\(\dfrac{1}{8.9.10}\)) . x = \(\dfrac{22}{45}\)
Tìm x nha mọi người mình đang cần gấp lắm ạ
tim so tu nhien x biet (1/1.2.3+1/2.3.4+...+1/8.9.10)x=22/45
Tim so tu nhien x biet (1/1.2.3+1/2.3.4+...1/8.9.10)x=22/45
tim so tu nhien x biet (1/1.2.3+1/2.3.4+...+1/8.9.10)x=22/45
Tìm x biết :
\(\left(\frac{1}{1.2.3}+\frac{1}{2.3.4}+...+\frac{1}{8.9.10}\right).x=\frac{22}{45}\)
tìm số TN x biết
(1/1.2.3+1/2.3.4+...+1/8.9.10)x=22/45
đang cần gấp nên mình sẽ cho 2 tick
