Answer:


x=8

Step by step explanation:

Solve for x in the following equation:


\log _x(1)/(512)=-3

We can apply logarithm properties:


(\ln((1)/(512)))/(\ln(x))=-3

Multiply both sides by ln(x):


\begin{gathered} (\ln((1)/(512)))/(\ln(x))\cdot\ln (x)=-3\ln (x) \\ \end{gathered}

Then, solve for x:


\begin{gathered} \ln ((1)/(512))=-3\ln (x) \\ e^{\ln ((1)/(512))}=e^(-3\ln (x)) \\ x=8 \\ \end{gathered}
