Use algebra to simplify the expression before evaluating the limit. In particular, factor the highest power of $n$ from the numerator and denominator, then cancel as many factors of $n$ as possible. If the sequence does not converge, enter diverges in the final answer box. $\displaystyle{\lim_{n \to \infty} \frac{ 3 n }{ (7 n^{5} + 5 )^{1/ 5 } } = \lim_{n \to \infty} \bigg(}$ $\displaystyle{\bigg) = }$ .
