Question

Determine the derivative of g(x) = √[x](x^3 - x)

Answer 1

\[g(x)= x^{\frac{5}{2}}-x^{\frac{3}{2}}\]
\[g'(x)= \frac{5}{2}x^{\frac{3}{2}}-\frac{3}{2}x^{\frac{1}{2}}\]

\[g'(x)= \frac{3\sqrt{x^3}}{2}-\frac{3\sqrt{x}}{2}\]

Answer 2

The answer at the back says this:
[rootx]/2 (7x^2 - 3)
I got what you got as well..
