tính nhanh giá trị biểu thức :M= \(\frac{\frac{3}{5}+\frac{3}{7}-\frac{3}{11}}{\frac{4}{5}+\frac{4}{7}-\frac{4}{11}}\)
Tính nhanh: M = \(\frac{75-\frac{6}{13}+\frac{3}{17}-\frac{3}{19}}{275-\frac{22}{13}+\frac{11}{17}-\frac{11}{19}}\)
giúp mik mn
bài 1:tính tổng M=\(3\frac{1}{417}\cdot\frac{1}{762}-\frac{1}{139}\cdot4\frac{761}{76}-\frac{4}{417-762}+\frac{5}{139}\)
ai giải nhanh nhất mình tick
Tính tổng sau:
M=\(\frac{4}{1.5}-\frac{4}{5.9}-\frac{4}{9.13}-.....-\frac{4}{\left(n-4\right).n}\)
Ai nhanh mk tick
