a) Ta có: \(\frac{8n+5}{4n+1}=\frac{\left(8n+2\right)+3}{4n+1}=2+\frac{3}{4n+1}\)
Để BT nguyên
=> \(\frac{3}{4n+1}\inℤ\)<=> \(4n+1\inƯ\left(3\right)=\left\{\pm1;\pm3\right\}\)
Mà \(4n+1\equiv1\left(mod4\right)\)
=> \(4n+1\in\left\{1;-3\right\}\Rightarrow n\in\left\{0;-1\right\}\)

b) Ta có: \(7^6+7^5-7^4\)
\(=7^4\left(7^2+7-1\right)\)
\(=7^4\cdot55⋮55\)
