Solve the equation LaTeX:  \displaystyle \log_{8}(x + 4100)-\log_{8}(x + 68)=2 .

Using the quotient property of logarithms gives LaTeX:  \displaystyle \log_{8}\frac{x + 4100}{x + 68} = 2 . Making both sides of the equation exponents on the base LaTeX:  \displaystyle 8 gives LaTeX:  \displaystyle \frac{x + 4100}{x + 68}=64 . Clearing the fractions by multiplying by the LCD gives LaTeX:  \displaystyle x + 4100=64 x + 4352 . Isolating LaTeX:  \displaystyle x gives LaTeX:  \displaystyle x = -4 .
