Answer
We notice that as the exponent of 2 approaches $\sqrt 3$, the value of the expression gets closer to $2^{\sqrt 3}$.
Work Step by Step
$2^{1.7}=3.24901$
$2^{1.732}=3.32188$
$2^{1.73205}=3.322$
$2^{1.7320508}=3.322$
We notice that as the exponent of 2 approaches $\sqrt 3$, the value of the expression gets closer to $2^{\sqrt 3}$.
