So sánh:
\(A=1.3.5.7...97.99\)
\(B=\frac{51}{2}.\frac{52}{2}.\frac{53}{2}.\frac{54}{2}...\frac{99}{2}.\frac{100}{2}\)
so sánh 1.3.5.7....99 với d=51/2 .52/2 .53/2 .....100/2
SO Sánh
R= 1.3.5.7...99 và S= 51/2. 52/2. 53/2... 100/2
so sánh
A= 1.3.5.7....99
B= 51/2 .52/2 . 53/3 .... 100/2
Chứng minh
\(1.3.5.7...99=\frac{51}{2}.\frac{52}{2}.....\frac{100}{2}\)
Tính ;\(\frac{1.3.5.7...99}{\frac{51}{2}.\frac{52}{2}...\frac{100}{2}}\)
CHứng tỏ:
1.3.5.7.9...97.99 = 51/2 . 52.2 . 53/2 ... 99/2 . 100/2
C= 1.3.5.7..99 với D= \(\frac{51}{2}.\frac{52}{2}.\frac{53}{2}...\frac{100}{2}\)
so sánh C=\(\frac{51}{2}.\frac{52}{2}\frac{53}{2}........\frac{100}{2}\)D=1.3.5.7....99
