Answer 1

Answer:

 x^3

-------------            

  16 y^5 z

Step-by-step explanation:

4^-2 x^3 y^-5 z^-1

negative exponents flip

x^3                            x^3

-------------            = -------------

4^2  y^5  z^1           16 y^5 z

Answer 2

$4^{-2}x^3y^{-5}z^{-1}=\dfrac{1}{4^2}\cdot x^3\cdot\dfrac{1}{y^5}\cdot\dfrac{1}{z^1}=\boxed{\dfrac{x^3}{16y^5z}}\\\\Used:\\\\a^{-n}=\dfrac{1}{a^n}$
