Answer 1

Answer:

The answer to your question is the last choice

Step-by-step explanation:

                               $(4z^{8})^{-3}$

Process

1.- Use the exponent law "Power"

                               $4^{-3} z^{(8)(-3)}$

2.- Simplify

                               $4^{-3} z^{-24}$

3.- Use the exponent law "Negative exponent"

                               $\frac{1}{4^{3} z^{24}}$

                               $\frac{1}{64z^{24}}$

4.- Conclusion    

He should have applied the exponent -3 to 4 to get   $\frac{1}{64z^{24}}$
