a)cho a,b,n thuoc N*.hay so a=n/b=n va a/b so sanh
b)choA=10^11-1/10^12-1;B=10^10+1/10^11+1.So sanh A va B
ho a=10 mu 11 -1 tren 10 mu 12 -1 va b= 10 mu 10 +1 tren 10 mu 11 +1. so sanh a va b
a, Cho a, b , n thuoc N*. Hay so sanh a + n/ b + n voi a/b
B Cho A= 1011 - 1/ 1012 - 1 va B= 1010+ 1/ 1011+ 1. Hay so sanh Avoi B
So sanh A va B biet:
\(A=\frac{10^{11}-1}{10^{12}-1}\) va \(B=\frac{10^{10}-1}{10^{11}-1}\)
AI NHANH MIK TIK, MIK CAN GAP!!!
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
a)Cho a,b,n thuoc N*.Hay so sanh\(\frac{a+n}{b+n}\) va \(\frac{a}{b}\)
b)Cho A=\(\frac{10^{11}-1}{10^{12}-1}\)
B=\(\frac{10^{10}+1}{10^{11}+1}\)
Hay so sanh A va B
a) cho a,b,n thuoc N* hay so sanh \(\frac{a+n}{b+n}va\frac{a}{b}\)
b) cho A=\(\frac{10^{11}-1}{10^{12}-1}\); B= \(\frac{10^{10}+1}{10^{11}+1}\)so sánh A và B
So sánh:
A = 1011 - 1/ 1012 - 1 va B = 1010+ 1/ 1011+ 1
so sanh
\(\frac{10^{11}-1}{10^{12}-1}và\frac{10^{10+1}}{10^{11}+1}\)
