\(\left(1-\frac{1}{97}\right)x\left(1-\frac{1}{98}\right)x....x\left(1-\frac{1}{1000}\right)\)
chú ý: \(x\) là dấu nhân nhé
Cần gấp gấp nha ai làm thì đầy đủ lời giải mình sẽ tick
\(\left(1-\frac{1}{97}\right)x\left(1-\frac{1}{98}\right)x...x\left(1-\frac{1}{1000}\right)\)
tính:\(\left(1-\frac{1}{97}\right)\times\left(1-\frac{1}{98}\right)\times...\times\left(1-\frac{1}{1000}\right)=\)
\(\left(1-\frac{1}{97}\right)\times\left(1-\frac{1}{98}\right)\times...\times\left(1-\frac{1}{1000}\right)=?\)
Tính:\(A=\left(1-\frac{1}{97}\right)\times\left(1-\frac{1}{98}\right)\times...\times\left(1-\frac{1}{1000}\right)\)
Tĩm x:
1,\(\frac{1}{\left(x+1\right)\left(x+2\right)}+\frac{1}{\left(x+2\right)\left(x+3\right)}+\frac{1}{\left(x+3\right)\left(x+4\right)}+\frac{1}{\left(x+4\right)\left(x+5\right)}=\frac{1}{x+5}\)
2,\(\left(x+\frac{1}{1.3}\right)+\left(x+\frac{1}{3.5}+......+x+\frac{1}{23.25}\right)=11.x+\left(\frac{1}{3}+\frac{1}{9}+\frac{1}{27}+\frac{1}{81}+\frac{1}{243}\right)\)
Giải chi tiết hộ mình nha mình tik cho
\(\left(1-\frac{3}{4}\right).\left(1-\frac{3}{7}\right).\left(1-\frac{3}{10}\right).\left(1-\frac{3}{13}\right).....\left(1-\frac{3}{97}\right).\left(1-\frac{3}{100}\right)\)
Tính nhanh:
\(\left(1+\frac{1}{100}\right)\cdot\left(1+\frac{1}{99}\right)\cdot\left(1+\frac{1}{98}\right)\cdot...\cdot\left(1+\frac{1}{2}\right)\)
. là nhân nhé còn ... là vâng vâng
Tính \(\left(1+\frac{1}{2}\right)+\left(1+\frac{1}{3}\right)+\left(1+\frac{1}{4}\right)+...+\left(1+\frac{1}{98}\right)+\left(1+\frac{1}{99}\right)\)
