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!
