Question

7x=2 es sobre ecuacion exponencial

Answer 1

$7^x=2 \\ \\ \ln \left(7^x\right)=\ln \left(2\right) \\ \\ x\ln \left(7\right)=\ln \left(2\right) \\ \\ \dfrac{x\ln \left(7\right)}{\ln \left(7\right)}=\dfrac{\ln \left(2\right)}{\ln \left(7\right)} \\ \\ \boxed{x=\frac{\ln \left(2\right)}{\ln \left(7\right)}}$
