Hello, qbkr21!
I didn't go through all your steps . . . ack!
. . . . . . . . . . . . . . _ . . . .5
Given: . f(x) .= .4x√x + ------ .= .4x^{3/2) + 5x^{-3/2}
. . . . . . . . . . . . . . . . . x√x
Then: . f'(x) .= .6x^{1/2} - (15/2)x^{-5/2}
I posted my work through the link:

He does not want us to simplify the answer.
Thanks For All of Your Help!
But in your spare time sir could you just look over them. Dr. W doesn't want me using the differentiate button on my calculator. He says that's cheating. My professor just wants us to drop the equation into the formula then move on. In this case Soroban multiple formula's (Product Rule, Quotient Rule, Product Rule)...
Hello, qbkr21!
What part of my explanation don't you understand?
Does it look like I just pressed a button?Dr. W doesn't want me using the differentiate button on my calculator.
. . Did I type all that Algebra and Calculus for nothing?
I'm worried about Dr W . . .

If he gave you: . f(x) .= .-------
. . . . . . . . . . . . . . . . . . . x²
would he expect you to use the Quotient Rule and Chain Rule?
. . (and "don't simplify"?)
or are you allowed to simplify first?
