We have: \(36,5,m,n\in Z^+\)
\(\Rightarrow36^m,5^n\in Z^+\)
\(\Rightarrow36^m\ge36^1=36;5^n\ge5^1=5\)
\(\Rightarrow36^m-5^n\ge36-5=31\)
\(\Rightarrow\left(36^m-5^n\right)_{Min}=31\Leftrightarrow m=n=1\)

Sorry Dao Trong Luan for the wrong title. Can you do it again?
\(\left|36^m-5^n\right|\).
If it's the last title, we have m = 1 and n big [unsolved]
