Cho A =\(\frac{3}{2}\)+\(\frac{13}{12}\)+\(\frac{31}{30}\)+...+\(\frac{9901}{9900}\),B=\(\frac{5}{6}\)+\(\frac{19}{20}\)+\(\frac{41}{42}\)+...+\(\frac{10099}{10100}\).Tính A-B
Tính A-B biết
A=3/2+13/12+31/30+...+9901/9900
B=5/6+19/20+41/42+...+10099/10100
B=5/6+19/20+41/42+......+10099/10100 và C= 3/2+13/12+31/30+..........+9901/9900
Tính C - B
\(A=\frac{7}{6}+\frac{13}{12}+\frac{21}{20}+\frac{31}{30}+...+\frac{9901}{9900}\)
\(B=\frac{2}{3}+\frac{5}{6}+\frac{9}{10}+\frac{14}{15}+...+\frac{4949}{4950}\)
Cho A= \(\frac{3}{2}+\frac{13}{12}+\frac{31}{30}+\frac{57}{56}+\frac{91}{90}\)
B= \(\frac{5}{6}+\frac{19}{20}+\frac{41}{42}+\frac{71}{72}+\frac{109}{110}\)
Tính A-B
A=
\(A=\frac{3}{2}-\frac{5}{6}+\frac{13}{12}-\frac{21}{20}+\frac{31}{30}-\frac{41}{42}+\frac{57}{56}-\frac{71}{72}+\frac{91}{90}-\frac{109}{110}\)
Tính \(A=\frac{1}{2}+\frac{5}{6}+\frac{11}{12}+\frac{19}{20}+\frac{29}{30}+\frac{41}{42}+\frac{55}{56}+\frac{71}{72}+\frac{89}{90}\)
tính\(A=\frac{1}{2}+\frac{5}{6}+\frac{11}{12}+\frac{19}{20}+\frac{29}{30}+\frac{41}{42}+\frac{55}{56}+\frac{71}{72}+\frac{89}{90}\)
Tính:
\(A=\frac{1}{2}+\frac{5}{6}+\frac{11}{12}+\frac{19}{20}+\frac{29}{30}+\frac{41}{42}\)
