  1. Solving Equations

  2. To Solve Log and Exponential Equations • Get the exponential/logarithmic expression on one side by itself • Try to get both bases to be the same • Take the log or ln of both sides and apply the properties of logs to solve the equation • Use the calculator

  3. Ex. 1 Solving Exponential and Logarithmic Equations Problem Rewritten Solution a) b) c)

  4. Ex. 1 Solving Exponential and Logarithmic Equations Problem Rewritten Solution d) e) f)

  5. Ex. 2 Solve each Equation

  6. Ex. 3 Solve Divide both sides by 4 Take logarithm of both sides Inverse Property Solve for x (multiply both sides by ) Use a calculator

  7. Ex. 4 Solve Add 4 to both sides Divide both sides by 2 Take log (base 3) of each side Inverse property Add 5 to each side Divide both sides by 2 Use a calculator

  8. Ex. 6 Solving Logarithmic Equations To solve a logarithmic equation, you write it in exponential form.

  9. Ex. 7 Solve Subtract 5 from both sides Divide both sides by 2 Exponentiate each side. Inverse Property Use a calculator

  10. Ex. 8 Solve Divide both sides by 2 Exponentiate each side Inverse property Divide both sides by 3
