 Find the derivative of y = x^x

Since the exponent is also a variable we can not use power rule instead we can take logarithm on both sides

y = x^x

Taking log on both sides

log y = log x^x

log y = x log x.      ( log a^b = b log a )

Differentiating both sides wrt x

1/y dy/ dx = x •1/x + log x • 1.         ( using product rule )

dy/dx = y ( 1 + log x )

dy/ dx = x^x ( 1+ log x ).                  ( by substituting back y = x^x )
