Question

como se calcula 2^y=3?

Answer 1

$\mathsf{~Aplicando~\ell og~em~ambos~os~lados~da~igualdade:}\\\\ \begin{array}{l}\mathsf{2^y=3}~\Leftrightarrow~\mathsf{\ell og2^y=\ell og3~\Leftrightarrow~y\ell og2=\ell og3~\Leftrightarrow~\dfrac{y\ell og2}{\ell og2}=\dfrac{\ell og3}{\ell og2}}\\\\\fbox{ \mathsf{y=\ell og_23} }~~\checkmark\end{array}$
