$A=\left(1+\dfrac{1}{2}\right)\times\left(1+\dfrac{1}{3}\right)\times\left(1+\dfrac{1}{4}\right)\times...\times\left(1+\dfrac{1}{100}\right)$

$\Rightarrow A=\dfrac{3}{2}\times\dfrac{4}{3}\times\dfrac{5}{4}\times\text{}\text{}\text{}...\times\dfrac{101}{100}$

$\Rightarrow A=\dfrac{101}{2}$

Câu trả lời:

$A=\left(1+\dfrac{1}{2}\right)\times\left(1+\dfrac{1}{3}\right)\times\left(1+\dfrac{1}{4}\right)\times...\times\left(1+\dfrac{1}{100}\right)$

Nguyễn Hoàng Tùng · Answer

$A=\left(1+\dfrac{1}{2}\right)\left(1+\dfrac{1}{3}\right)...\left(1+\dfrac{1}{100}\right)$

$A=\dfrac{3}{2}.$$\dfrac{4}{3}$...$\dfrac{101}{100}$

$A=\dfrac{101}{2}$

Câu trả lời:

$A=\left(1+\dfrac{1}{2}\right)\left(1+\dfrac{1}{3}\right)...\left(1+\dfrac{1}{100}\right)$

$A=\dfrac{3}{2}.$$\dfrac{4}{3}$...$\dfrac{101}{100}$

$A=\dfrac{101}{2}$
