\(A=\frac{3}{3}.\left(\frac{1}{2.5}+\frac{1}{5.8}+\frac{1}{8.11}+\frac{1}{11.14}+\frac{1}{14.17}+\frac{1}{17.20}\right)\)
\(A=\frac{1}{3}.\left(\frac{3}{2.5}+\frac{3}{5.8}+\frac{3}{8.11}+\frac{3}{11.14}+\frac{3}{14.17}+\frac{3}{17.20}\right)\)
\(A=\frac{1}{3}.\left(\frac{1}{2}-\frac{1}{20}\right)=\frac{3}{20}\)
S = 1/10 + 1/40 + 1/88 + 1/154 + 1/238 + 1/340
1/10 + 1/40 + 1/88 + 1/154 + 1/238 + 1/340
A=1/10+1/40+1/88+1/154+...+1/238+1/340
viết lới giải ra nhé thank
Tính \(A=\frac{1}{10}+\frac{1}{40}+\frac{1}{88}+\frac{1}{154}+\frac{1}{238}+\frac{1}{340}\)
Tính A = \(\frac{1}{10}+\frac{1}{40}+\frac{1}{88}+\frac{1}{154}+\frac{1}{238}+\frac{1}{340}\)
Tính
A= \(\frac{1}{10}+\frac{1}{40}+\frac{1}{88}+\frac{1}{154}+\frac{1}{238}+\frac{1}{340}\)
A = 1/10 + 1/40 + 1/88 + 1/154 + 1/238 + 1/340
B = 3/4 . 8/9 .15/16. ... 9999/10000
Bài 6 : Tim tong sau :
S = 1/10 + 1/40 + 1/88 + 1/154 + 1/238 + 1/340
Bài 6 : Tim tong sau :
S = 1/10 + 1/40 + 1/88 + 1/154 + 1/238 + 1/340
