Answer:
[tex]m ^ { 4 } +2m ^ { 3 } +3m ^ { 2 } +4m+5 \div m+4 \\ \\ \frac{\left(m^{4}+2m^{3}+3m^{2}+4m+4\right)m}{m}+\frac{5}{m} \\ \\ \frac{\left(m^{4}+2m^{3}+3m^{2}+4m+4\right)m+5}{m} \\ \\ \frac{m^{5}+2m^{4}+3m^{3}+4m^{2}+4m+5}{m} \\ [/tex]
[tex]2n ^ { 4 } +4n ^ { 3 } -n ^ { 2 } +7n+2 \div n-4 \\ \\ \frac{\left(2n^{4}+4n^{3}-n^{2}+7n-4\right)n}{n}+\frac{2}{n} \\ \\ \frac{\left(2n^{4}+4n^{3}-n^{2}+7n-4\right)n+2}{n} \\ \\ \frac{2n^{5}+4n^{4}-n^{3}+7n^{2}-4n+2}{n} [/tex]
