Tìm x: \(\left(x+\frac{1}{2}\right)+\left(x+\frac{1}{4}\right)+\left(x+\frac{1}{8}\right)+\left(x+\frac{1}{16}\right)=1\)
\(\left(x+\frac{1}{2}\right)+\left(x+\frac{1}{4}\right)+\left(x+\frac{1}{8}\right)+\left(x+\frac{1}{16}\right)=1\)\(1\). Tìm x
tìm x
\(\left(x+\frac{1}{2\cdot4}\right)+\left(x+\frac{1}{4\cdot6}\right)+\left(x+\frac{1}{6\cdot8}\right)+\left(x+\frac{1}{8\cdot10}\right)+\left(x+\frac{1}{10\cdot12}\right)=50\frac{5}{24}\)
Tìm T:
\(T=\left(1-\frac{1}{4}\right)X\left(1-\frac{1}{9}\right)X\left(1-\frac{1}{16}\right)X...X\left(1-\frac{1}{576}\right)X\left(1-\frac{1}{625}\right)\)
Mk đang cần gấp
\(\left(1-\frac{1}{4}\right)X\left(1-\frac{1}{9}\right)X\left(1-\frac{1}{16}\right)X.......X\left(1-\frac{1}{144}\right)X\left(1-\frac{1}{169}\right)\)
Tính bằng cách hợp lí:
a/ \(\left(1+\frac{1}{3}\right)x\left(1+\frac{1}{8}\right)x\left(1+\frac{1}{15}\right)x...x\left(1+\frac{1}{9999}\right)\)
b/ \(\left(1-\frac{1}{4}\right)x\left(1-\frac{1}{9}\right)x\left(1-\frac{1}{16}\right)x...x\left(1-\frac{1}{10000}\right)\)
Nhớ giải giúp mình nhé!
Tìm T biết :
T = \(\left(1-\frac{1}{4}\right)x\left(1-\frac{1}{9}\right)x\left(1-\frac{1}{16}\right)x....x\left(1-\frac{1}{576}\right)x\left(1-\frac{1}{625}\right)\)
Tìm x
(\(\left(1+\frac{1}{2}\right)x\left(1+\frac{1}{3}\right)x\left(1+\frac{1}{4}\right)x...x\left(1+\frac{1}{x}\right)=1008\frac{1}{2}\)
tìm x
\(\left(1-\frac{1}{2}\right)x\left(1-\frac{1}{3}\right)x\left(1-\frac{1}{4}\right)x.......x\left(1-\frac{1}{10}\right)=\frac{x}{2010}\)
