Answer:
[tex]-125\ z^3[/tex]
Step-by-step explanation:
To simplify:
[tex](-5\ z)^3[/tex]
Using Power of product rule [ [tex](a\ b)^x=a^xb^x[/tex] ]
⇒ [tex](-5)^3(z)^3[/tex]
Evaluating the numerical powers.
⇒ [tex](-5\times -5 \times -5)\ z^3[/tex]
⇒ [tex]-125\ z^3[/tex]
The expression cannot be simplified any further, so that would be the final form.
