so sanh \(y\frac{10^{6+1}}{10^{5+1}}\)va\(y\frac{10^{7+1}}{10^{6+1}}\)
1so sanh \(y=\frac{10^6+1}{10^{5+1}}\)va \(y\frac{10^{7+1}}{10^{6+1}}\)2x
so sanh cac phan so sau: 10^6+1/10^5+1 va 10^7+1/10^6+1
so sanh 2 PS sau
\(\frac{7^{10}+1}{7^{10}-1}\)va \(\frac{7^{10}-1}{7^{10}-3}\)
So sanh A va B
A = 1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7 +1/8 + 1/9 +1/10
B = 23/10
Tính giúp em với ạ
a)Cho a,b,n thuoc N*.Hay so sanh$\frac{a+n}{b+n}$a+nb+n va $\frac{a}{b}$ab
b)Cho A=$\frac{10^{11}-1}{10^{12}-1}$1011−11012−1
B=$\frac{10^{10}+1}{10^{11}+1}$1010+11011+1
Hay so sanh A va B
So sanh A va B, biet :
a)\(A=\frac{1+5+5^2+...+5^9}{1+5+5^2+...+5^8};B=\frac{1+3+3^2+...+3^9}{1+3+3^2+...+3^8}\)
b)\(A=\frac{7^{10}}{1+7+7^2+...+7^9};B=\frac{5^{10}}{1+5+5^2+...+5^9}\)
SO SANH \(\frac{10^{19}+1}{10^{20}+1}\) VA \(\frac{10^{20}+1}{10^{21}+1}\)
So sanh A va B biet:
\(A=\frac{10^{11}-1}{10^{12}-1}\) va \(B=\frac{10^{10}-1}{10^{11}-1}\)
