Answer:

  • [tex]\cfrac{n^{10}}{144m^4}[/tex]

Step-by-step explanation:

  • [tex](\cfrac{3m^{-5}n^2}{4m^{-2}n^0})^2* (\cfrac{mn^4}{9n})^2=[/tex]
  • [tex](\cfrac{3m^{-5}n^2mn^4}{4m^{-2}n^09n})^2=[/tex]
  • [tex](\cfrac{m^{-5+1+2}n^{2+4-0-1}}{4*3})^2=[/tex]
  • [tex](\cfrac{m^{-2}n^5}{12})^2=[/tex]
  • [tex](\cfrac{n^5}{12m^2})^2=[/tex]
  • [tex]\cfrac{n^{10}}{144m^4}[/tex]
