Answer
We notice that as the exponent of 2 approaches $\pi$, the value of the expression gets closer to $2^{\pi}$.
Work Step by Step
$2^3=8$
$2^{3.1}=8.54719$
$2^{3.14}=8.81524$
$2^{3.141}=8.82135$
$2^{3.1415}=8.82441$
$2^{3.14159}=8.82496$
$2^{3.141593}=8.82498$
We notice that as the exponent of 2 approaches $\pi$, the value of the expression gets closer to $2^{\pi}$.
