**Hint:**Differentiation of function means to compute the derivative of that function. A derivative is the rate at which output changes with respect to an input. We will suppose the given value as $\left( {y = {x^x}} \right)$.

**Complete step by step solution:**

$ y = {x^x} $

Taking log both sides, we will get

$ \log y = \log {x^x} $

We know that by the property of logarithm that $ {\text{log(m}}{{\text{)}}^{\text{a}}}{\text{ = a log m}} $

\[ \Rightarrow \log \,y = x{\text{ }}log{\text{ }}x\]

Differentiating this value with respect to x, we have

$

\dfrac{1}{y}\dfrac{d}{{dx}}y = x\dfrac{d}{{dx}}\log x + \log x\dfrac{d}{{dx}}x \\

\dfrac{1}{y}\dfrac{{dy}}{{dx}} = x \times \dfrac{1}{x} \times \dfrac{d}{{dx}}x + \log x \times 1 \\

\dfrac{1}{y}\dfrac{{dy}}{{dx}} = x \times \dfrac{1}{x} \times 1 + \log x \\

\dfrac{1}{y}\dfrac{{dy}}{{dx}} = 1 + \log x \\

$

\[\dfrac{1}{y}\,\,\dfrac{{dy}}{{dx}} = 1 + \log x\,\,\]

$ \dfrac{{dy}}{{dx}} = y\left( {1 + \log x} \right) $

\[\dfrac{{dy}}{{dx}} = {x^x}\left( {1 + \log \,x} \right)\] \[\left( {\because y = {x^x}} \right)\]

**Note:**In these types of questions students must take care while calculating the differentiation of \[log\,x\]. Usually students forget to calculate the derivative $ \left( {\dfrac{d}{{dx}}} \right) $ the value \[log\,x\] with respect to their function.
