Simplify the expression 2x^-17 / x^3z for x = 2, y = 8, and z =-1. Type a numerical answer is the space provided. If necessary, use the / key to represent a fraction bar. Do not type spaces in your answer.
See the attached picture. I did it with the second x as the y value since there was a y value given but no y in the equation. I figured that may have been a typo.
