# $0^0$

Calculus Level 2

$0^0$ is often defined as equal to $1$ since $\displaystyle\lim_{x\to 0^+}x^x=1$.

This led a mathematician to claim that $\displaystyle\lim_{x\to 0^+}f(x)^{g(x)}=1$ for all $f(x)$ and $g(x)$ whenever $\displaystyle\lim_{x\to 0^+}f(x)=\displaystyle\lim_{x\to 0^+}g(x)=0$.

Is this claim true?
