simplify and evaluate ( 4x^2x^3y^2-z^-3/x^5 y^8z^9)2?

Answer 1

(4x^2x^3y^2-z^-3/x^5 y^8z^9)2
=(4x^2*x^3* y^2 -z^-3x^-5*y^8*z^9)2
= (4 x^0 *y^8 * z^6)2
= (4y^8z^6)2
= 8y^8z^6 , if the 2 means multiply, or
= 16 y^16z^12, if the two means raise to 2nd power.

Answer 2

You beat me to the answer, ironduke8159.
Now I am sad... :(
