**Question:**I copied and pasted the question the way that it was presented to me 1. Simplify and evaluate:

(4^2x^3y^-2z^-3/x^-5y^8z^-9)^2

**Answers:**

Let's rewrite this so it's a little easier to read:

(4^2 * x^3 * y^-2 * z^-3 / x^-5 * y^8 * z^-9)^2. (what a mess!)

= (16 * x^8 * z^6 / y^10)^2 = 256 *x^16 * z^12 / y^20. OK?
