Answer

$-\frac{1}{4x \sqrt{x}}+(e^x)(ln x + \frac{2x-1}{x^2})$

Work Step by Step

$g(x)=\sqrt{x}+e^x ln x$ $u=e^x$ $u’=e^x$ $v=ln x$ $v’=\frac{1}{x}$ $g’(x)=\frac{1}{2}x^{-\frac{1}{2}}+(e^x)(ln x)+\frac{e^x}{x}$ $=\frac{1}{2\sqrt{x}}+e^{x}(ln x+\frac{1}{x})$ $u=e^x$ $u’=e^x$ $v=ln x+ \frac{1}{x}$ $v’=\frac{1}{x}-\frac{1}{x^2}$ $g’’(x)=-\frac{1}{4}x^{-\frac{3}{2}}+(e^x)(ln x+\frac{1}{x})+(e^x)(\frac{x-1}{x^2})$ $=-\frac{1}{4x \sqrt{x}}+(e^x)(ln x + \frac{2x-1}{x^2})$
