WebThen replace both side with 10 raised to the power of each side, to get log(x)/log(3) = 2. Then multiply through by log(3) to get log(x) = 2*log(3). Then use the multiplication property from the prior video to convert the right side to get log(x) = log(3^2). Then replace both sides with 10 raised to the power of each side again, to get x = 3^2 = 9. WebSolving Exponential Equations with Logarithms. Exponential equations can be solved by taking the log of both sides. Steps: 1) As much as possible, get the log by itself. 2) Take the log (or natural log) of both sides. 3) Simplify as needed using the log rules. 4) Solve the equation for the variable. Examples:
