Answer:
The step wise solution is shown below:
Step-by-step explanation:
[tex](3x^{-7} y z^{-3} ) (3x)^{-4}[/tex]
= [tex](3x^{-7} (3x)^{-4} y z^{-3} )[/tex]
= [tex]3^{1-4} x^{-7-4} y z^{-3}[/tex]
= [tex]3^{-3} x^{-11} yz^{-3}[/tex]
= [tex]\frac{y}{3^{3} x^{11}z^{3} }[/tex]
= [tex]\frac{y}{27 x^{11}z^{3} }[/tex]
