Hi Michael,

Solving this problem requires the use of exponent rules and how to work with fractions.

First, let's take a look at the denominator: n^(3-n)

We can apply our knowledge of exponent division to get: (n^3)/(n^n)

So we have 6/[(n^3)/(n^n)].

Using the basics of fractions, we can rewrite this as (6*n^n)/(n^3)

Apply exponent division again, and we've gotten rid of the fraction to get: 6n^(n-3)

This is the simplified version of the original expression.

You can check your work by choosing numbers for n and finding the value of the original and simplified expressions.

Do a search for "exponent rules" and "properties of fractions" for some additional information and practice problems. You might consider making a study guide with the exponent rules and some examples.

Good luck!

Katherine
