I…well okay I’m feeling useless today so I’ll just give you the answer.
You know how to derive though right?
Using the product rule?
E.g.
Derivative of UxV
is the (derivative of U)multiplied by (V) plus (U)multiplied by(derivative of V)

And the quotient rule.
Derivative of U/V
(D. of U)(V)-(U)(D. of V)
All over V^2

Muuuuuhhh sooo.
End answer…

10.5x^(3/2) - ((5x^2)/(2^0.5))
