Re: Derivative Help!
What have you tried? I would express the variables with exponents, simplify, and take the derivative from there:
\(\displaystyle f(x) = -3x^{5} \sqrt{x} + \frac{4}{x^{2} \sqrt{x}}\)
\(\displaystyle f(x) = -3x^{5}x^{\frac{1}{2}} + 4x^{-2}{x^{-\frac{1}{2}}\)
\(\displaystyle f(x) = -3x^{\left(5 + \frac{1}{2}\right)} + 4x^{\left(-2-\frac{1}{2}\right)}\)
etc.
