We could differentiate it as a quotient but it's a
little easier to first turn it into a product:
A clever trick we often play here is to factor out the smallest exponent, the
power.
When we factor the power out of the power what's left inside is
the difference of the exponents
It's just the first power!
We factor out:
We write the negative exponent in the bottom as a positive exponent:
