Detail solution
  1. Apply the product rule:

    ddxf(x)g(x)=f(x)ddxg(x)+g(x)ddxf(x)\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}

    f(x)=exf{\left(x \right)} = e^{x}; to find ddxf(x)\frac{d}{d x} f{\left(x \right)}:

    1. The derivative of exe^{x} is itself.

    g(x)=log(x)2g{\left(x \right)} = \log{\left(x \right)}^{2}; to find ddxg(x)\frac{d}{d x} g{\left(x \right)}:

    1. Let u=log(x)u = \log{\left(x \right)}.

    2. Apply the power rule: u2u^{2} goes to 2u2 u

    3. Then, apply the chain rule. Multiply by ddxlog(x)\frac{d}{d x} \log{\left(x \right)}:

      1. The derivative of log(x)\log{\left(x \right)} is 1x\frac{1}{x}.

      The result of the chain rule is:

      2log(x)x\frac{2 \log{\left(x \right)}}{x}

    The result is: exlog(x)2+2exlog(x)xe^{x} \log{\left(x \right)}^{2} + \frac{2 e^{x} \log{\left(x \right)}}{x}

  2. Now simplify:

    (xlog(x)+2)exlog(x)x\frac{\left(x \log{\left(x \right)} + 2\right) e^{x} \log{\left(x \right)}}{x}


The answer is:

(xlog(x)+2)exlog(x)x\frac{\left(x \log{\left(x \right)} + 2\right) e^{x} \log{\left(x \right)}}{x}
