10101. (5/11111 5/22222- 4/3.7.11.13.37)
10101 nhân (5/11111 + 5/22222- 4/3.7.11.13.37)
help me!!!!!!!!!!!!!!!!!!!!!!!!
10101 x ( 10/22222 + 5/22222 - 8/22222 ) =20202/22222
Tính: \(10101\times\left(\frac{5}{11111}+\frac{5}{22222}-\frac{4}{3\times7\times11\times13\times17}\right)\)
ko có cách nào tính ra đâu chỉ có thể bấm máy tính thôi
10101.(5/111111+5/222222-4/3.7.11.13.37)
C=10101.(5/111111 + 5/222222 + 4/3.7.11.13.37 ) = ?
\(C=10101.\left(\frac{5}{111111}+\frac{5}{222222}+\frac{4}{3.7.11.13.37}\right)\)
\(C=10101.\frac{23}{222222}\)
\(C=\frac{23}{22}.\)
C=10101.(5/111111 + 5/222222 + 4/3.7.11.13.37 )
Tính nhanh
10101.(5/111111 + 5/222222 + 4/3.7.11.13.37)
10101.(\(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{3.7.11.13.37}\))
111111=3.7.11.13.37
222222=2.3.7.11.13.37

\(I=10101.\left(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{3.7.11.13.37}\right)\)
B= 10101.\(\left(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{3.7.11.13.37}\right)\)
\(B=10101\cdot\left(\dfrac{5}{111111}+\dfrac{5}{222222}-\dfrac{4}{111111}\right)\)
\(=10101\cdot\left(\dfrac{2}{222222}+\dfrac{5}{222222}\right)\)
\(=10101\cdot\dfrac{1}{31746}=\dfrac{7}{22}\)
