Dalam Nama Bapa dan Putera dan Roh Kudus. Amin.
Remember that anything to the power of zero always yields 1; that is how it is defined.
Excuse me ... .

$x^0=1$ if $x\neq0$ ... .
If $x=0$, then $x^0=0^0$ is undetermined ... because
$\displaystyle\lim_{x\rightarrow0^+}0^x=0$, and $\displaystyle\lim_{x\rightarrow0^-}0^x$ is undetermined ... .
But, however, $\displaystyle\lim_{x\rightarrow0}x^0=1$ ... .
Agnus Dei, qui tollis peccata mundi.
