17n = 174 : 289
=> 17n = 174 : 172
=> 17n = 172
=> n = 2
17n=174:289
17n=83521:289
17n=289
17n=171
n=1
17n = 174 : 289
17n = 174 : 172
17n = 174-2
17n = 172
Vậy n = 2
17n = 174 : 289
17n = 174 : 172
17n = 172
=> n = 2
Ta có 289=172
=> 17n =174: 172
=> 17n = 172
=> n=2
17n = 174 : 289
\(\Rightarrow\)17n = 174 : 172
17n = 174 - 2
17n = 172
\(\Rightarrow\) n = 2
17n = 174 : 289
17n = 174 : 172
17n = 174-2
17 n = 172
=> n = 2
