Giải chi tiết hộ mình nha mình tik cho
a)\(\left(1-\frac{1}{2}\right)x\left(1-\frac{1}{3}\right)x\left(1-\frac{1}{4}\right)x\left(1-\frac{1}{5}\right)x......x\left(1-\frac{1}{18}\right)x\left(1-\frac{1}{19}\right)x\left(1-\frac{1}{20}\right)\)
b)\(1\frac{1}{2}x1\frac{1}{3}x1\frac{1}{4}x1\frac{1}{5}x......x1\frac{1}{2005}x1\frac{1}{2006}x1\frac{1}{2007}\)
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!
