Tính \(1\frac{1}{2}+2\frac{2}{3}+3\frac{3}{4}+4\frac{4}{5}+...+50\frac{50}{51}+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{51}\)
\(1\frac{1}{2}+2\frac{2}{3}+3\frac{3}{4}+...+50\frac{50}{51}+\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...\frac{1}{51}\)
tính
\(-\frac{1}{3}+\frac{1}{3^2}-\frac{1}{3^3}+\frac{1}{3^4}-....+\frac{1}{3^{50}}-\frac{1}{3^{51}}\)
tính: \(-\frac{1}{3}+\frac{1}{3^2}-\frac{1}{^{3^3}}+.....+\frac{1}{3^{50}}-\frac{1}{3^{51}}\)
Tính B=\(-\frac{1}{3}+\frac{1}{3^2}-\frac{1}{3^3}+...+\frac{1}{3^{50}}-\frac{1}{3^{51}}\)
Tính B=\(-\frac{1}{3}+\frac{1}{3^2}-\frac{1}{3^3}+.......+\frac{1}{3^{50}}-\frac{1}{3^{51}}\)
Tính: \(B=-\frac{1}{3}+\frac{1}{3^2}-\frac{1}{3^3}+...+\frac{1}{3^{50}}-\frac{1}{3^{51}}\)
Tính B= \(-\frac{1}{3}+\frac{1}{3^2}-\frac{1}{3^3}+...+\frac{1}{3^{50}}-\frac{1}{3^{51}}\)
