Vì \(20^{10}-1>20^{10}-3\)
\(\Rightarrow B=\frac{20^{10}-1}{20^{10}-3}>\frac{20^{10}-1+2}{20^{10}-3+2}=\frac{20^{10}+1}{20^{10}-1}=A\)
vậy \(A< B\)
So sánh A và B:
\(A=\frac{20^{10}+1}{20^{10}-1};B=\frac{20^{10}-1}{20^{10}-3}\)
So sánh A=\(\frac{20^{10}+1}{20^{10}-1}\)và B=\(\frac{20^{10}-1}{20^{10}-3}\)
So sánh A và B
A = \(\frac{20^{10}+1}{20^{10}-1}\)Và B = \(\frac{20^{10}-1}{20^{10}-3}\)
So sánh : \(A =\frac{20^{10} +1}{20^{10}-1} ; B =\frac{20^{10} -1}{20^{10} -3}\)
So Sánh \(A=\frac{20^{10}+1}{20^{10}-1}\text{và }B=\frac{20^{10}-1}{20^{10}-3}\)
So sánh
A= \(\frac{20^{10}+1}{20^{10}-1}\) và B= \(\frac{20^{10}-1}{20^{10}-3}\)
so sánh \(A=\frac{20^{10}+1}{20^{10}-1};B=\frac{20^{10}-1}{20^{10}-3}\)
So sánh \(A=\frac{20^{10}+1}{20^{10}-1}\)và\(B=\frac{20^{10}-1}{20^{10}-3}\)
So sánh A và B:
a,A=\(\frac{10^{2004}+1}{10^{2005}+1}\)
B=\(\frac{10^{2005}+1}{10^{2006}+1}\)
b,A=\(\frac{20^{10}+1}{20^{10}-1}\)
B=\(\frac{20^{10}-1}{20^{10}-3}\)
