Answer:
$3zx^2y^3\sqrt[3]{3xz^2}$

Step-by-step explanation:

$\sqrt[3]{81x^7y^9z^5}$ =

$\sqrt[3]{27*3x^(6+1)y^9z^(3+2)}$ =

$\sqrt[3]{3^3*3x*x^6y^9z^3z^2}$ =

$\sqrt[3]{3^3*3x*(x^2)^3(y^3)^3z^3z^2}$ =

$\sqrt[3]{3^3*(x^2)^3(y^3)^3z^3*3x*z^2}$ =

$\sqrt[3]{(3zx^2y^3)^3*3x*z^2}$ =
$3zx^2y^3\sqrt[3]{3xz^2}$
