Se a elevado a x= N então X é igual a:

Answer 1

$\text a^{\text x}=\text N \\\\ \underline{\text{aplicando log }_{\text a} \ \text{dos dois lados }}: \\\\ \text{log }_{\text{a }}\text a^{\text x}=\text{log }_{\text{a }}\text N \\\\ \text x.\text{log }_{\text{a }}\text a = \text{log }_{\text{a }}\text N \\\\ \text x.1=\text{log }_{\text{a }}\text N \\\\ \huge\boxed{\text x = \text{log }_{\text{a }}\text N \ }\checkmark$
