\(A=\frac{79}{1999}+\frac{191}{1998}+\frac{947}{1997}+\frac{673}{1998}+\frac{110}{1999}\)
\(A=\left(\frac{79}{1999}+\frac{110}{1999}\right)+\left(\frac{191}{1998}+\frac{673}{1998}\right)+\frac{947}{1997}\)
\(A=\frac{189}{1999}+\frac{16}{37}+\frac{947}{1997}\)
cho A=\(\frac{79}{1999}+\frac{191}{1998}+\frac{947}{1997}+\frac{673}{1998}+\frac{110}{1999}\)
so sánh A với 1
Cho A=79/1999+191/1998+947/1997+673/1998+110/1999
tính A=\(\frac{79}{1999}\)+\(\frac{191}{1998}\)+\(\frac{947}{1997}\)+\(\frac{6733}{1998}\)+\(\frac{110}{1999}\)???
a) A= 79/1999 + 191/1998 + 947/1997 + 673/1998 + 110/1999.
Hãy so sánh A với 1
b) tính:
M= 1 + 1/2 + 1/2^2 + .......+ 1/2^99 + 1/2^100 + 1/2^100.
Tính
A=\(\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+.....+\frac{1}{2000}}{\frac{1999}{1}+\frac{1998}{2}+\frac{1997}{3}+......+\frac{1}{1999}}\)
Ai nhanh và đúng mình tick cho
\(\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{20}}{\frac{1999}{1}+\frac{1998}{2}+\frac{1997}{3}+...+\frac{1}{1999}}\)
\(E=\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{2000}}{\frac{1999}{1}+\frac{1998}{2}+\frac{1997}{3}+..+\frac{1}{1999}}\)
Tính \(E=\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{2000}}{\frac{1999}{1}+\frac{1998}{2}+\frac{1997}{3}+...+\frac{1}{1999}}\)
\(T\text{ính}:\frac{\frac{1}{2}+\frac{1}{3}+\frac{1}{4}+...+\frac{1}{2000}}{\frac{1999}{1}+\frac{1998}{2}+\frac{1997}{3}+...+\frac{1}{1999}}\)
