Math Problem,.. (Simplifying),.. plz help?

Question

((x^2)(y^3)) / ((x^5)(y)(z^-1)) (x/z)^3

its easier to write it on paper

thank you

Answer 1

First get them all over the same fraction bar and work out minus powers, then combine and cancel.
((x^2)(y^3)) / ((x^5)(y)(z^-1)) (x/z)^3 = ((x^2)(y^3)(z)(x^3)) / ((x^5)(y)(z^3)) = y^2/z^2.

Answer 2

((x^2)(y^3)) / ((x^5)(y)(z^-1)) (x/z)^3

(y^2) / ((x^3)(z^-1)) (x/z)^3

(y^2) / ((x^6) / (z^4))
