Attach an exponent to the base number to make the equation true.

Rewrite $$\log_25$$  to base 10

Rewrite $$\log_25$$  to base 9

Use the change of base formula to evaluate each expression. Round to four decimal places. Show your work. $$\log_261$$  

Use the change of base formula to evaluate each expression. Round to four decimal places. Show your work. $$\log_{11}136$$  

$$12\log\left(3x-1\right)=36$$  

$$4\log_5\left(x-1\right)-3=9$$  

$$\log_{18}\left(10-2b\right)=\log_{18}\left(5b-4\right)$$
