a, Ta có : \(10^{15}\cdot11=10^{15}\left(10+1\right)=10^{16}+10^{15}\)
Vì \(10^{16}+10^{15}>10^{16}+10\)
\(\Rightarrow\dfrac{10^{16}+10^{15}}{10^{16}+1}>\dfrac{10^{16}+10}{10^{16}+1}\)
Hay A>B
b, Ta có : \(C=\dfrac{10^{10}+1}{10^{10}-1}=\dfrac{10^{10}}{10^{10}-1}+\dfrac{1}{10^{10}-1}\)
\(D=\dfrac{10^{10}-1}{10^{13}-3}=\dfrac{10^{10}}{10^{13}-3}+\dfrac{-1}{10^{13}-3}\)
Vì \(\dfrac{10^{10}}{10^{10}-1}>\dfrac{10^{10}}{10^{13}-3};\dfrac{1}{10^{10}-1}>\dfrac{-1}{10^{13}-3}\)
\(\Rightarrow\dfrac{10^{10}+1}{10^{10}-1}>\dfrac{10^{10}-1}{10^{13}-3}\)
Hay C > D
TRƯỚC TIÊN TA SO SÁNH 10 VỚI 10B
10A=10^16+10/10^16+1=1\(\frac{9}{16+1}\)
10B=10^17+10/10+17+1=1\(\frac{9}{17+1}\)
VÌ 9/16+1>9/17+1
=>10A>10B
=>A>B
AI TÍCH MK ;MK TÍCH LẠI
Đặt \(A=\frac{10^{15}+1}{10^{16}+1}\Rightarrow10A=\frac{10^{16}+10}{10^{16}+1}=1+\frac{9}{10^{16}+1}\)
Đặt \(B=\frac{10^{16}+1}{10^{17}+1}\Rightarrow10B=\frac{10^{17}+10}{10^{17}+1}=1+\frac{9}{10^{17}+1}\)
Vì \(10^{16}+1< 10^{17}+1\Rightarrow\frac{9}{10^{16}+1}>\frac{9}{10^{17}+1}\)
\(\Rightarrow10A>10B\Rightarrow A>B\)
\(\Rightarrow\frac{10^{15}+1}{10^{16}+1}>\frac{10^{16}+1}{10^{17}+1}\)
B = 10^16+1/10^17+1 < 10^16 + 1 + 9 / 10^17+1+9 = 10^16+10/10^17+10
= 10(10^15+1) / 10(10^16+1)
= 10^15 + 1 / 10^15 + 1 = A
=> A > B
SO SANH 10A ;10B\
10A=10^16+10/10^16+1
=1+\(\frac{9}{10^{16}}\) +1
10B =10^17+10/10^17+1
=1+\(\frac{9}{10^{17+1}}\)
=>9/10^16>10^17+1
=>10A>10B
=>A>B
