Question

So sanh : A=1.3.5.7...99 va B =51/2.52/2...100/2

Answer 1

\(A=\frac{1.2.3...........99.100}{2.4.6....100}\)

\(=\frac{1.2.3..............99.100}{1.2.2.2.2.3.........50.2}\)

\(=\frac{1.2.3.......50........99.100}{\left(1.2.3........50\right).2.2.....2}\)

\(=\frac{51.52..........99.100}{2.2............2}\)

\(=\frac{51}{2}.\frac{52}{2}...........\frac{100}{2}\)

Answer 2

\(\Rightarrow A=B\)
