tìm x
2x +7/6+13/12+21/20+31/30+43/42+57/56+73/72+91/90=10
TÌm x biết : 2x +7/6+13/12+21/20+31/30+43/42+57/56+73/72+91/90 = 0
Tìm x : \(2x+\frac{7}{6}+\frac{13}{12}+\frac{21}{20}+\frac{31}{30}+\frac{43}{42}+\frac{57}{56}+\frac{73}{72}+\frac{91}{90}=10\)10
tìm x biết \(2x+\frac{7}{6}+\frac{13}{12}+\frac{21}{20}+\frac{31}{30}+\frac{43}{42}+\frac{57}{56}+\frac{73}{72}+\frac{91}{90}=10\)
1.Tìm x, biết: x+13/12+21/20+31/30+43/42+57/56+73/72+91/90=277/30
Tìm x,y biết:
a) 1/5.8+1/8.11+1/11.14+...+1/y(y+3).=98/1545
b) 2x+7/6+13/12+21/20+31/30+43/42+57/56+73/72+91/90 = 0
Tìm y biết: 2x+7/6+13/12+21/20+31/30+43/42+57/56+73/72+91/90=10. Bạn nào giải hộ mình nhanh với, mình cần gấp
Tìm x biết :
a) \(\frac{1}{2013}\times x+1+\frac{1}{2}+\frac{1}{6}+\frac{1}{12}+...+\frac{1}{2012\times2013}=2\)
b)\(2x+\frac{7}{6}+\frac{13}{12}+\frac{21}{20}+\frac{31}{30}+\frac{43}{42}+\frac{57}{56}+\frac{73}{72}+\frac{91}{90}=10\)
giải gúp tôi bài này với x+13/12+21/20+31/30+43/42+57/56+73/72+91/90
ai làm được tôi sẽ tích thật nhiều cho
