​Example:

Draw

Rewrite each equation in exponential form:  $$\log_{12}12=1$$  

Draw

Rewrite each equation in logarithmic form: $$8^{\frac{2}{3}}=4$$  

Draw

Rewrite the equation in exponential form:  $$\log_{\frac{1}{4}}4=-1$$  

Draw

Rewrite each equation in logarithmic form: $$6^{-3}=\frac{1}{216}$$
