Como se desarrolla estas operacion:
1. $${{\mathtt{5}}}^{{\mathtt{x}}} = {{\mathtt{8}}}^{{\mathtt{x}}}$$
2. $${{\mathtt{9}}}^{{\mathtt{x}}}{\mathtt{\,-\,}}{\mathtt{4}}{\mathtt{\,\times\,}}{{\mathtt{3}}}^{{\mathtt{x}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}} = {\mathtt{0}}$$
3. $${{\mathtt{3}}}^{\left({{\mathtt{x}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{12}}\right)} = {\mathtt{1}}$$
