im asked to Simplify the given expression to rational exponent form and justify each step by identifying the properties of rational exponents use

mathstudent55 · Answer

Ok.

Here are some rules of exponents that we need.

$\large a^{-n} = \dfrac{1}{a^n} $

$\large a^{\frac{m}{n}} = \sqrt[n]{a^m} = \left(\sqrt[n]{a}\right)^m$

mathstudent55 · Answer

Let's start with the denominator.
We can use the second rule to write the root as a rational exponent.
Try that and show what you get.
Remember, we are only working n the denominator for now.
