Answer 1

\(\left(1000-1^3\right)\left(1000-2^3\right)\left(1000-3^3\right)....\left(1000-50 ^3\right)\)

\(=\left(1000-1^3\right)\left(1000-2^3\right)...\left(1000-10^3\right)......\left(1000-50^3\right)\)

\(=\left(1000-1^3\right)\left(1000-2^3\right)...\left(1000-1000\right)......\left(1000-50^3\right)\)

\(=\left(1000-1^3\right)\left(1000-2^3\right)....0.....\left(1000-50^3\right)\)

\(=0\)
