2⁴+√4×3-2

$${{\mathtt{2}}}^{{\mathtt{4}}}{\mathtt{\,\small\textbf+\,}}{\sqrt{{\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,-\,}}{\mathtt{2}}}} = {\mathtt{19.162\: \!277\: \!660\: \!168\: \!379\: \!3}}$$

 

$${{\mathtt{2}}}^{{\mathtt{4}}}{\mathtt{\,\small\textbf+\,}}{\sqrt{{\mathtt{4}}{\mathtt{\,\times\,}}{\mathtt{3}}}}{\mathtt{\,-\,}}{\mathtt{2}} = {\mathtt{17.464\: \!101\: \!615\: \!137\: \!754\: \!6}}$$

 

$${{\mathtt{2}}}^{{\mathtt{4}}}{\mathtt{\,\small\textbf+\,}}{\sqrt{{\mathtt{4}}}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,-\,}}{\mathtt{2}} = {\mathtt{20}}$$

Thanks Radix :))

There you go, a multiple choice answer for a multiple choice question.  :)
