Question

\(1\frac{1}{2}\)X \(1\frac{1}{3}\)x\(1\frac{1}{4}\)x...x\(1\frac{1}{2015}\)

Answer 1

      \(1\frac{1}{2}x1\frac{1}{3}x1\frac{1}{4}x..........x1\frac{1}{2015}\)

\(=\frac{3}{2}x\frac{4}{3}x\frac{5}{4}x.........x\frac{2016}{2015}\)

\(=\frac{2016}{2}=1008\)

Answer 2

Nhưng tại sao lại ra \(\frac{2016}{2}\)

Answer 3

\(\frac{3}{2}x\frac{4}{3}x\frac{5}{4}x.....x\frac{2016}{2015}=\frac{3x4x5x...x2016}{2x3x4x....x2015}=\frac{2016}{2}=1008\)

Answer 4

Tại sao lại ra \(\frac{2016}{2}\) có ai trả lời cho mik bik với
