d/dxpi^x = pi^xln(pi)

Explanation:

d/dxpi^x = d/dx e^ln(pi^x)

=d/dxe^(xln(pi))

=e^(xln(pi))(d/dxxln(pi))

(By applying the chain rule with the functions e^x and xln(pi))

=e^ln(pi^x)ln(pi)

=pi^xln(pi)

Note that this method can be generalized to show that d/dxa^x = a^xln(a) for any constant a>0
