Convertir un nombre de la base 2 à la base 10. $$ (0101)_2 = (...)_{10} $$
$$ ({\color{black}{0}}{\color{orange}{1}}{\color{blue}{0}}{\color{red}{1}})_2 = {\color{red}{1\cdot 2^{0}}}{\color{blue}{+0\cdot 2^{1}}}{\color{orange}{+1\cdot 2^{2}}}{\color{black}{+0\cdot 2^{3}}} = {\color{red}{1}}{\color{blue}{+0}}{\color{orange}{+4}}{\color{black}{+0}} = 5 $$
