Answer 1

\(\left(1000-1^3\right)\left(1000-2^3\right).............\left(1000-25^3\right)\)

\(=\left(1000-1^3\right)\left(1000-2^3\right)........\left(1000-10^3\right)......\left(1000-25^3\right)\)

\(=\left(1000-1^3\right)\left(1000-2^3\right)......\left(1000-1000\right)......\left(1000-25^3\right)\)

\(=\left(1000-1^3\right)\left(1000-2^3\right)........0.......\left(1000-25^3\right)\)
