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
[tex]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}[/tex]
