Rewrite the function using a rational exponent, then use the power rule: and so:
So, for the second derivative you would use the quotient rule right? And how would that work? You would have to find the derivative of which I believe is ... am I on the right track?

Learning that form can be a great time saver.
Awesome, that is a cool way to think of it!
