Ta có:
134012 = 132.2006 = (132)2006 = 1692006
Vì 1313 > 169 và 2006 > 0 nên 13132006 > 1692006 hay 13132006 > 134012

a)
\(\frac{13}{27}=\frac{13.101}{27.101}=\frac{1313}{2727}\)
=> \(\frac{13}{27}=\frac{1313}{2727}\)
b)
\(-\frac{15}{23}=-\frac{15.10101}{23.10101}=-\frac{151515}{232323}\)
=>\(-\frac{15}{23}=-\frac{151515}{232323}\)
a) \(\frac{1313}{2727}=\frac{1313:101}{2727:101}=\frac{13}{27}\)
Vậy \(\frac{13}{27}=\frac{1313}{2727}\)
b) \(-\frac{151515}{232323}=\frac{-151515:10101}{232323:10101}=-\frac{15}{23}\)
Vậy \(-\frac{15}{23}=-\frac{151515}{232323}\)

Ta có : \(1-\frac{2012}{2013}=\frac{1}{2013}\);\(1-\frac{2011}{2012}=\frac{1}{2012}\)
Mà \(\frac{1}{2013}< \frac{1}{2012}\)
Vậy\(\frac{2012}{2013}>\frac{2011}{2012}\)
Muốn so sánh phân số thì chúng ta quy đồng về mẫu số chung
\(\frac{2012}{2013}=\frac{2012.2012}{2013.2012}=\frac{4048144}{4050156}\)
\(\frac{2011}{2012}=\frac{2011.2013}{2012.2013}=\frac{4048143}{4050156}\)
Vì 2048144 > 4048143 \(\left(\frac{4048144}{4050156}>\frac{4048143}{4050156}\right)\) . Nên \(\frac{2012}{2013}>\frac{2011}{2012}\)

a, \(\frac{1313}{2727}=\frac{13\cdot101}{27\cdot1001}=\frac{13}{27}\)
b,\(\frac{151515}{232323}=\frac{15.10101}{23.10101}=\frac{15}{23}\)

Ta có :
\(1313^{2006}=13^{2006}.101^{2006}>13^{2006}.13^6=13^{2012}\)
\(\Rightarrow1313^{2006}>13^{2012}\)
