Question

Resolva a equação exponencial
7³x =343

Answer 1

✅ Após resolver a equação exponencial, concluímos que o valor de "x" é:

       $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf x = 1\:\:\:}}\end{gathered} }$

   

Resolvendo equação exponencial:

          $\Large\displaystyle\begin{gathered} 7^{3x} = 343\end{gathered}$

          $\Large\displaystyle\begin{gathered} {\!\backslash\!\!\!7}^{3x} = {\!\backslash\!\!\!7}^{3}\end{gathered}$

           $\Large\displaystyle\begin{gathered} 3x = 3\end{gathered}$

              $\Large\displaystyle\begin{gathered} x = \frac{3}{3}\end{gathered}$

              $\Large\displaystyle\begin{gathered} x = 1\end{gathered}$

✅ Portanto, o valor de "x" é:

              $\Large\displaystyle\begin{gathered} x = 1\end{gathered}$

$\LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{\:\:\:Bons \:estudos!!\:\:\:Boa\: sorte!!\:\:\:}}}\end{gathered} }$
