Hello, Amanda!

This one of the more unpleasant functions to differentiate.

I suggest using the Quotient Rule.

. . Those negative exponents can be dangerous.

It starts simply enough . . .

. . If there is a coefficient, I "pull it out front".

Now it gets**very**messy . . . simplify each derivative before continuing.

There were at least opportunities to make errors.

. . I don't guarentee any of my results.
