Solve the equation LaTeX:  \displaystyle \log_{4}(x + 258)-\log_{4}(x + 66)=1 .

Using the quotient property of logarithms gives LaTeX:  \displaystyle \log_{4}\frac{x + 258}{x + 66} = 1 . Making both sides of the equation exponents on the base LaTeX:  \displaystyle 4 gives LaTeX:  \displaystyle \frac{x + 258}{x + 66}=4 . Clearing the fractions by multiplying by the LCD gives LaTeX:  \displaystyle x + 258=4 x + 264 . Isolating LaTeX:  \displaystyle x gives LaTeX:  \displaystyle x = -2 .
