Answer:

your answer will be option A

Step-by-step explanation:

(8w^7x^-5y^3z^-9)-2/3

= (8)-2/3×(w^7)^-2/3×(x^-5)^-2/3×(y^3)^-2/3×(z^-9)-2/3

=(2^3)^-2/3×w^-14/3×x^10/3

xy^-2xz^6

=2^-2 w^-14/3 x^10/3 y^-2 xz^6

=1/4×1/w^14/3× x^10/3 xz^6/y^2

=x^10/3z^6/4w14/3y^2

hope it helps..

have a great day!!
