\(1\frac{1}{2}.1\frac{1}{3}.1\frac{1}{4}....1\frac{1}{1963}\)\(=\frac{3}{2}.\frac{4}{3}.\frac{5}{4}.\frac{6}{5}......\frac{1964}{1963}\)\(=\frac{3.4.5.6.....1964}{2.3.4.5.....1963}=\frac{1964}{2}=982\)
1 1/2 x 1 1/3 x 1 1/4 x .......x 1 1/1963
=3/2 x 4/3 x 5/4 x...x1964/1963
=1964/2
=982
Trả lời :
\(1\frac{1}{2}.1\frac{1}{3}.1\frac{1}{4}...1\frac{1}{1963}\)
=\(\frac{3}{2}.\frac{4}{3}.\frac{6}{5}...\frac{1964}{1963}\)
=\(\frac{3.4.5.6...1964}{2.3.4.5...1963}\)
=\(\frac{1964}{2}=982\)

\(1\frac{1}{2}\times1\frac{1}{3}\times1\frac{1}{4}\times...\times1\frac{1}{1963}\)
\(=\frac{3}{2}\times\frac{4}{3}\times\frac{5}{4}\times...\times\frac{1964}{1963}\)
\(=\frac{1964}{2}\)
\(=982\)
