3.1
$\frac{ {m}^{7} }{m - 5} \div \frac{ {m}^{4} }{ {m}^{4} - 10 { {m}^{3} } + 25 {m}^{2} } = \\ \\ \frac{ {m}^{7} }{m - 5} \times \frac{( {m}^{2} - 5m) {}^{2} }{ {m}^{4} } = \\ \\ \frac{m {}^{3} \times (m(m - 5)) {}^{2} }{m - 5} = \\ \\ \frac{ {m}^{5}(m - 5) {}^{2} }{m - 5} = \\ \\ m {}^{5} (m - 5) = {m}^{6} - 5 {m}^{5}$

$\frac{ {m}^{2} - 25 }{ {m}^{6} } \times \frac{m {}^{8} }{m {}^{2} + 5m} \div ( {m}^{2} + 25 - 10m) = \\ \\ \frac{(m - 5)(m + 5) \times {m}^{2} }{m(m + 5)} \times \frac{1}{(m - 5) {}^{2} } = \\ \\ \frac{ m }{m - 5}$
