\(\frac{33.10^3}{2^3.5.10^3+7000}=\frac{33.10^3}{40.10^3+7.10^3}=\frac{33.10^3}{10^3.47}=\frac{33}{47}\)
\(\frac{3774}{5217}=\frac{34}{47}\)
Do đó VT<VP
33.103/23.5.103+7000<3774/5217
So sánh
\(\frac{1}{3}+\frac{2}{3^2}+\frac{3}{3^3}+\frac{4}{3^4}+...+\frac{100}{3^{100}}vs\frac{3}{4}\)
So sánh:
\(\frac{1}{3}+\frac{1}{3^2}+\frac{1}{3^3}+...+\frac{1}{3^{100}}với\frac{1}{2}\)
so sánh \(a=\frac{1}{2^2}+\frac{1}{2^3}+\frac{1}{2^4}+...+\frac{1}{199^2}với\frac{3}{4}\)
so sánh \(\left(\frac{1}{3}+\frac{1}{3^2}+\frac{1}{3^3}+.............+\frac{1}{3^{99}}\right)và\frac{1}{2}\)
\(\frac{1}{3}+\frac{1}{3^2}+\frac{1}{3^3}+..+\frac{1}{3^{99}}+\frac{1}{3^{100}}\) và \(\frac{1}{2}\)
So sánh
\(A=\frac{1}{3}+\frac{2}{3^2}+\frac{3}{3^3}+\frac{4}{3^4}+....+\frac{101}{3^{101}}\)
So sánh Avới \(\frac{3}{4}\)
Hãy so sánh : \(\frac{1}{2!}+\frac{2}{3!}+\frac{3}{4!}+\frac{4}{5!}+....+\frac{99}{100!}\) và 1
cho S = \(\frac{2}{2^1}+\frac{3}{2^2}+\frac{4}{2^3}+.....+\frac{2010}{2^{2009}}+\frac{2011}{2^{2010}}\)
SO SÁNH S VỚI 3
Xét tổng T= \(\frac{2}{2^1}+\frac{3}{2^2}+\frac{4}{2^3}+...+\frac{2015}{2^{2014}}\).Hãy so sánh T với 3
