We are given the function to differentiate:


{\quad \qquad \sf \rightarrow y=x^(e^x)}

Do take natural log on both sides, then we will be having


{:\implies \quad \sf ln(y)=ln(x^{e^(x)})}


{:\implies \quad \sf ln(y)=e^(x)ln(x)\quad \qquad \{\because ln(a^b)=bln(a)\}}

Now, differentiate both sides by using so called chain rule and the product rule


{:\implies \quad \sf (1)/(y)(dy)/(dx)=e^(x)ln(x)+(e^x)/(x)}


{:\implies \quad \boxed{\bf{(dy)/(dx)=x^(e^x)\bigg\{(e^x)/(x)+ln(x)e^(x)\bigg\}}}}

Hence, Option B) is correct

Product rule of differentiation:


  • {\boxed{\bf{(d)/(dx)(uv)=u(dv)/(dx)+v(du)/(dx)}}}

Where, u and v are functions of x
