Step 1
Step 1:** Condense the left side of the equation: \[ \log_a{(x+13)} - \log_a{(x-5)} = 1 \] \[ \log_a{\left(\frac{x+13}{x-5}\right)} = 1 \] ** Show more…

Solve each logarithmic equation. Be sure to reject any value of $x$ that is not in the domain of the original logarithmic expressions. Give the exact answer. Then, where necessary, use a calculator to obtain a decimal approximation, correct to two decimal places, for the solution. $\log _{5} x=3$
Solve each logarithmic equation. Express all solutions in exact form. Support your solutions by using a calculator. $$\log x+\log (3 x-13)=1$$
