B=(6/8+1)(6/18+1)(6/30)...(6/10700+1)
Tính nhanh E=\(\frac{6}{8+1}.\frac{6}{18+1}.\frac{6}{30+1}...\frac{6}{10700+1}\)
1.tính nhanh :(6/8+1).(6/18+1).(6/30+1)...(6/10700+1)
2.chứng minh rằng :A=1/2!+1/3!+1/4!+...+1/1000!
Cho:
D=(6/8+1)*(6/18+1)*(6/30+1)*...*(6/10700+1)
Tính D
Tính nhanh:
F=\(\left(\frac{6}{8}+1\right)\left(\frac{6}{18}+1\right)\left(\frac{6}{30}+1\right).....\left(\frac{6}{10700}+1\right)\)
Tính :
\(A=\left(\frac{6}{8}+1\right)\left(\frac{6}{18}+1\right)\left(\frac{6}{30}+1\right)...\left(\frac{6}{10700}+1\right)\)
Giúp cái !!!
Tính giá trị
(6/8 +1)×(6/30 +1)...(6/10700 +1)
Tính: A=\(\left(\frac{6}{8}+1\right)\cdot\left(\frac{6}{18}+1\right)\cdot\left(\frac{6}{30}+1\right)\cdot...\cdot\left(\frac{6}{10700}+1\right)\)
Tính giá trị biểu thức sau :
\(B=\left(\frac{6}{8}+1\right)\left(\frac{6}{18}+1\right)\left(\frac{6}{30}+1\right)...\left(\frac{6}{10700}+1\right)\)
