CTR : 3/4 + 8/9 + 15/16 + 24/25 +....+ 2499/2500 > 48
* Giúp mình với :(
Tính
A=\(\frac{8}{9}+\frac{15}{16}+\frac{24}{25}+...+\frac{2499}{2500}\)
Tính :\(y=\frac{8}{9}.\frac{15}{16}.\frac{24}{25}...\frac{2499}{2500}\)
Tính A=\(\frac{8}{9}.\frac{15}{16}.\frac{24}{25}....\frac{2499}{2500}\)
Tính:
\(\frac{8}{9}.\frac{15}{16}.\frac{24}{25}...\frac{2499}{2500}\)
Rút gon: A= 8/9*15/16*24/25*...*2499/2500
giúp mk với nhé!
