Solve Exponential Equations by Taking the Log of Both Sides

Which method would you do to start solving the below exponential equation?

• Take Log, base 10, on the left hand side

• Take Log, base 3, on the left hand side

• Take Log, base e, on the both sides

• Help?!?

After taking logs on both sides of the previous equation, you get the below equation. What is the next step?

• Divide both sides by x

• Multiply both sides by Log(3)

• Distribute the Log(3) term

• Use the change of base formula to calculate Log3

• You didn't cover this, did you?
