\(C=\frac{\left(1+\frac{1999}{1}\right)\left(1+\frac{1999}{2}\right)...\left(1+\frac{1999}{1000}\right)}{\left(1+\frac{1000}{1}\right)\left(1+\frac{1000}{2}\right)...\left(1+\frac{1000}{1999}\right)}\)=> \(C=\frac{\frac{2000.2001.2002....2999}{1.2.3...1000}}{\frac{1001.1002.1003....2999}{1.2.3...1999}}\)

Tính: \(\left(1000-1^3\right).\left(1000-2^3\right).\left(1000-3^3\right)......\left(1000-50^3\right)=..........\)
Vì trong dãy trên sẽ có 1000-10\(^3\)=0
\(\Rightarrow\)(1000-1)(1000-2\(^3\))...(1000-50\(^3\))=0
Tính:
Ta có : 1000 - 13 = 1000 - 1000 = 0
Nên : (= 0
Vậy ...
Ta có: (1000 - 1^3) . (1000 - 2^3) . (1000 - 3^3) . ... . (1000 - 10^3) . ... . (1000 - 50^3)
= (1000 - 1^3) . (1000 - 2^3) . (1000 - 3^3) . ... . (1000 - 1000). ... . (1000 - 50^3)
= (1000 - 1^3) . (1000 - 2^3) . (1000 - 3^3) . ... . 0 . ... . (1000 - 50^3)
= 0
Tính : \(\left(1000-1^3\right).\left(1000-2^3\right).\left(1000-3^3\right).....\left(1000-50^3\right)=?\)
\(\left(1000-1^3\right).\left(1000-2^3\right).\left(1000-3^3\right)....\left(1000-50^3\right)\)
\(=\left(1000-1^3\right).\left(1000-2^3\right)...\left(1000-10^3\right)....\left(1000-50^3\right)\)
\(=\left(1000-1^3\right).\left(1000-2^3\right)...\left(1000-1000\right)....\left(1000-50^3\right)\)
\(=\left(1000-1^3\right).\left(1000-2^3\right)...0...\left(1000-50^3\right)\)
\(=0\)
