Answer 1

[Thanh Tùng DZ]

\(\frac{51.52.53...100}{1.3.5...99}\)

\(=\frac{\left(2.4.6...100\right).\left(51.52.53...100\right)}{\left(2.4.6...100\right).\left(1.3.5...99\right)}\)

\(=\frac{\left(2.4.6...100\right).\left(51.52.53...100\right)}{1.2.3.4.5.6...99.100}\)

\(=\frac{2.4.6...100}{1.2.3...50}\)

\(=\frac{\left(2.2...2\right).\left(1.2.3...50\right)}{1.2.3...50}\)

\(=2.2.2...2\)

\(=2^{50}\)
