chứng minh : 51/2 . 52/2 .... 100/2 = 1.3.5.....99
Chứng minh rằng:\(\frac{51}{2}+\frac{52}{2}+...+\frac{100}{2}=1.3.5...99\)
chung minh rang :
1.3.5. ... . 99 = 51/2 . 52/2 . ... . 100/2
1.3.5....99=51/2 .52/2.....100/2
Chứng minh rằng :
\(\frac{51}{2}\). \(\frac{52}{2}\). .... .\(\frac{100}{2}\)= 1.3.5. ... .99
CMR : 51/2 . 52/2 .....100/2 = 1.3.5......99
CMR : 51/2 . 52/2 ......100/2 = 1.3.5......99
cmr 1.3.5....99\(=\dfrac{51}{2}.\dfrac{52}{2}...\dfrac{100}{2}\)
Chứng tỏ rằng:
1.3.5...99=\(\frac{51}{2}.\frac{52}{2}...\frac{100}{2}\)
