$\lim\limits_{x\rightarrow 0}{x^x}=1$
What value can the $\delta$ be?
How about: pick any $x$ close to $0$, say, $\frac{1}{10^k}$,
$(\frac{1}{10^{k}})^{(\frac{1}{10^{k}})} = 10^{-\frac{k}{10^{k}}}$
Notice how as $k$ grows larger (and your $x$ gets closer to $0$), that exponent (on the RHS) gets closer and closer to zero. What is $\lim_{n\to 0} 10^{n}$?
