Answer:
[tex] \star→ \: { \sf{ \frac{ \{ {3y}^{8} - {4y}^{6} + {5y}^{4} \}}{ {y}^{3} } }} \\ [/tex]
• factorization:
[tex] \star→ \: { \sf{ \frac{ {y}^{3}(3y {}^{5} - 4 {y}^{3} + 5 {y} }{ {y}^{3} }}} \\ \\ \star→ \: { \sf{ \frac{ {y}^{3} }{ {y}^{3} } .^{}(3y {}^{5} - 4 {y}^{3} + 5 {y}}})[/tex]
• divide:
[tex] = { \boxed{ \boxed{ \sf{y(3 {y}^{4} - 4 {y}^{2} + 5)}}}}[/tex]
