\[g(x)=x^\sqrt{x} \] Find g'(x).

OpenStudy (michele_laino):

hint: we can rewrite such function as below: \[\huge g\left( x \right) = \exp \left( {\sqrt x \ln x} \right),\quad x > 0\]

OpenStudy (michele_laino):

or, using a different notation: \[\huge g\left( x \right) = {e^{\sqrt x \ln x}},\quad x > 0\]

OpenStudy (hpfan101):

Oh okay. So afterwards we use the product rule on the exponent part?

OpenStudy (michele_laino):

yes!

OpenStudy (hpfan101):

Okay did I do this part correctly? \[(\sqrt{x})'(lnx)+(\sqrt{x})(lnx)'=(1/2\sqrt{x})(lnx)+(\sqrt{x}/x) \]

OpenStudy (michele_laino):

that's right! Now you have to multiply such derivative by the same function \(g(x)\)

Ok, thank you!
