Chapter 4.6, Problem 71E

To determine

To find the expression that is not equivalent to $x^2·x^{-6}$

Answer to Problem 71E

B. $x^{-2}·x^6$

Explanation of Solution

Given information: Amongst the given options, $x^{-2}·x^6$ $\ne$ $x^2·x^{-6}$

Simplify the expression $x^2·x^{-6}$ , $x^{-4}$ .

However, on simplifying $x^{-2}·x^6$ it becomes $x^4$ .
