Ta có :3111 < 3211(hay 3111 < 255)
1714 > 1614(hay 1714 > 256)
Ta thấy :
256 > 255
=> 1714 > 3111
Ta có:
\(31^{11}< 32^{11}\Rightarrow31^{11}< \left(2^5\right)^{11}\Rightarrow31^{11}< 2^{55}\)
\(17^{14}>16^{14}\Rightarrow17^{14}>\left(2^4\right)^{14}\Rightarrow17^{14}>2^{56}\)
\(\Leftrightarrow31^{11}< 17^{14}\)
