Solve the equation LaTeX:  \displaystyle \log_{10}(x + 100022)-\log_{10}(x + 1022)=2 .

Using the quotient property of logarithms gives LaTeX:  \displaystyle \log_{10}\frac{x + 100022}{x + 1022} = 2 . Making both sides of the equation exponents on the base LaTeX:  \displaystyle 10 gives LaTeX:  \displaystyle \frac{x + 100022}{x + 1022}=100 . Clearing the fractions by multiplying by the LCD gives LaTeX:  \displaystyle x + 100022=100 x + 102200 . Isolating LaTeX:  \displaystyle x gives LaTeX:  \displaystyle x = -22 .
