Có \(A=\frac{10^{2017}+1-3}{10^{2017}+1}=1-\frac{3}{10^{2017}+1}\)
\(B=\frac{10^{2017}+3-3}{10^{2017}+3}=1-\frac{3}{10^{2017}+3}\)
Có 102017+1<102017+3
=> \(\frac{3}{10^{2017}+1}>\frac{3}{10^{2017}+3}\)
=>A<B
cho A=\(\frac{-2016}{10^{2016}}+\frac{-2017}{10^{2017}}\)
B=\(\frac{-2017}{10^{2016}}-\frac{2016}{10^{2017}}\)
so sánh A và B
so sánh 2 phân số sau:\(A=\frac{10^{2016}+10}{10^{2017}+10};B=\frac{10^{2017}-10}{10^{2018}-10}\)
So sánh:
\(A=\frac{10^{2016}+1}{10^{2017}+1}\) và \(B=\frac{10^{2017}+1}{10^{2018}+1}\)
So sánh A=\(\frac{10^{2017}+1}{10^{ }^{2016}+1}\)B=\(\frac{10^{2018}+1}{10^{2017}^{ }+1}\)
So sánh A=\(\frac{10^{2017}+1}{10^{2018}+1}\), B=\(\frac{10^{2016}+1}{10^{2017}+1}\)
So sánh A và B biết :
A = \(\frac{10^{2016}+1}{10^{2017}+1}\)
B = \(\frac{10^{2017}+1}{10^{2018}+1}\)
So sánh A và B, biết rằng:
A = \(\frac{10^{2017}+1}{10^{2018}+1}\)
Và B = \(\frac{10^{2016}+1}{10^{2017}+1}\)
so sánh
a, A=\(\frac{10^{17}-1}{10^{16}-1}vaB=\frac{10^{16}+2}{10^{15}+2}\)
b,\(C=\frac{2017^{15}+1}{2017^{16}+1}vaO=\frac{2017^{16}-1}{2017^{17}-1}\)
c,\(E=\frac{99^{15}-1}{99^{16}-1}vaF=\frac{99^{16}+2}{99^{17}+2}\)
a)Chứng minh rằng: \(\frac{200-\left(3+\frac{2}{3}+\frac{2}{4}+..+\frac{2}{100}\right)}{\frac{1}{2}+\frac{2}{3}+\frac{3}{4}+...+\frac{99}{100}}=2\)
b)\(A=\frac{-21}{10^{2016}}+\frac{-12}{10^{2017}};B=\frac{-12}{10^{2016}}+\frac{-21}{10^{2017}}\)
So sánh A và B
