\(\frac{2}{3}+\frac{14}{15}+\frac{34}{35}+\frac{62}{63}+...+\frac{9998}{9999}\)
Tính \(M=\frac{2}{3}+\frac{14}{15}+\frac{34}{35}+\frac{62}{63}+...+\frac{9998}{9999}\)
Tính M= 2/3+14/15+34/35+62/63+...+9998/9999

Tìm A :
1 / A = ( 1 -\(\frac{1}{3}\)) + ( 1 - \(\frac{1}{15}\)) + ( 1 - \(\frac{1}{35}\)) + ( 1 - \(\frac{1}{63}\))
2 / A = ( 1 -\(\frac{1}{10}\)) + ( 1 - \(\frac{1}{40}\)) + ( 1 - \(\frac{1}{88}\)) + ( 1 - \(\frac{1}{154}\))
3 / A = \(\frac{2}{3}+\frac{14}{15}+\frac{34}{35}+....+\frac{9998}{9999}\)
4 / A = \(\frac{9}{10}+\frac{39}{40}+\frac{87}{88}+...+\frac{1119}{1120}\)
5 / A = \(\frac{9}{10}+\frac{39}{40}+\frac{87}{88}+\frac{153}{154}\)
Trình bày cách làm hộ mình nha ! Cảm ơn rất nhiều !
Giúp mình với!
\(\left(\frac{9998}{9999}.\frac{11}{17}+\frac{9998}{9999}.\frac{7}{24}-\frac{19996}{19998}\right):\left(5\frac{11}{17}+\frac{7}{24}-6\right)\)
Cho A = \(\frac{1}{2}.\frac{3}{4}.\frac{5}{6}...\frac{9998}{9999}.\frac{10000}{10000}\)
So sánh A và 0,01
