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!!
Change 1 2/3 to 5/3 because it is easier to add and subtract fraction when they are improper. This makes -1/3-5/3, -1-5=-6, so the equation equals -6/3 which simplifies to -2.
