Answer:

[tex]d)\ \frac{81}{m^{7}}[/tex]

Step-by-step explanation:

[tex](3m^-4)^3(3m^5)[/tex]

First, simplify [tex](3m^{-4})^3[/tex]:

[tex](3m^{-4})^3\\\\3^3*m^{-4*3}\\\\27m^{-12}[/tex]

[tex]27m^{-12}*3m^5\\\\27*3 *m^{-12+5}\\\\81m^{-7}\\\\81*\frac{1}{m^{7}} \\\\\frac{81}{m^{7}}[/tex]

Hope this helps!
