CHO A=1/2^2+1/3^2+1/4^2+...+1/100^2 va B=1/4^2+1/6^2+1/8^2+.....+1/200^2khi do A/B=...
nhanh len cac ban oi
cho A=1/2.3/4.5/6........99/100 va B=2/3.4/5.5/6.........100/101 so sanh A va B
So sánh A ;B : \(A=\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+...+\frac{1}{100^2};B=\frac{1}{4^2}+\frac{1}{6^2}+\frac{1}{8^2}+...+\frac{1}{200^2}\)
So sánh \(A=\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+...+\frac{1}{100^2};B=\frac{1}{4^2}+\frac{1}{6^2}+...\frac{1}{200^2^{ }}\)
Cho A = 1/ 2^2 + 1/3^2 + 1/4^2 + .......+ 1/100^2 và B = 1/4^2 + 1/6^2 + 1/8^2 +........+ 1/200^2 . tính A/B = ........
A = 1/2^2 + 1/3^2 + 1/4^2 + ... + 1/100^2 và B = 1/4^2 + 1/6^2 + 1/8^2 + ...1/200^2. Khi đó A/B = ...
