10101x(\(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{3\times7\times11\times13\times37}\))
Tính: \(10101\times\left(\frac{5}{11111}+\frac{5}{22222}-\frac{4}{3\times7\times11\times13\times17}\right)\)
\(C=10101\left(\frac{5}{111111}+\frac{5}{222222}+\frac{4}{111111}\right)\)
\(I=10101.\left(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{3.7.11.13.37}\right)\)
\(A=10101.\left(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{3.7.11.13.37}\right)\)
\(10101.\left(\frac{5}{111111}+\frac{5}{222222}\frac{4}{3.7.11.13.37}\right)\)
\(C=10101\left(\frac{5}{111111}+\frac{5}{222222}+\frac{4}{3.7.11.13.37}\right)\)
\(C=10101\left(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{37.11.13.37}\right)\)=?
\(C=10101\left(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{3.7.11.13.37}\right)\)
