so sánh:A=20^10+1/20^10-1 và 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/ \(A=\dfrac{17^{18}+1}{17^{19}+1};B=\dfrac{17^{17}+1}{17^{18}+1}\)
b/ \(A=\dfrac{10^8-2}{10^8+2};B=\dfrac{10^8}{10^8+4}\)
c/ \(A=\dfrac{20^{10}+1}{20^{10}-1};B=\dfrac{20^{10}-1}{20^{10}-3}\)
GIÚP MÌNH VỚI
So sánh:A=\(\frac{20^{10}+1}{20^{10}-1}\) B=\(\frac{20^{10}-1}{20^{10}-3}\)
bai 1:tính nhanh : P=\(\frac{\frac{2}{3}-\frac{1}{4}+\frac{5}{11}}{\frac{5}{12}+1-\frac{7}{11}}\)
Bai 2:Thực hiện phép tính: 1-2+3-4+5-6+...+2011-2012
Bai 3:so sánh:A=\(\frac{2011+2012}{2012+2013}\)
B=\(\frac{2011}{2012}+\frac{2012}{2013}\)
bai4:so sánh:A=\(\frac{20^{10}+1}{20^{10}-1}\)
B=\(\frac{20^{10}-1}{20^{10}-3}\)
so sanh A=20^10+1/20^10-1 Va B=20^10-1/20^10-3
so sánh:
A= \(\dfrac{20^{10}+1}{20^{10}-1}\)và B=\(\dfrac{20^{10}-1}{20^{10}-3}\)
so sanh a=20^10/20^10-1 voi b=20^10-1/20^10-3
so sánh
A= 20^10+1/ 20^10-1 và B= 20^10-1/ 20^10-3
