take the function: y = x^x(adsbygoogle = window.adsbygoogle || []).push({});

if x<0; it is not defined. However:

take this example:

x=-3

therefore: y=(-3)^(-3)

=1 / ( (-3)^3 )

=-27

HOWEVER: y == e^(xln(x))

ln(x) has a domain: {x>0, x e R}

Thus in that respect when x=-3, it is undefined.

WHY???
