-10log₂ x + 8 = -12

• 8

• 12

• 1296

• 4

Convert 10^(x+5)=100 to logarithmic form.

• log₁₀₀=x+5

• log(x+5)=100

• log(100)=x+5

• log_(x+5)(100)=10

Which method would you use to solve this logarithmic equation?

• Method 1

  (Equate Logarithms)

• Method 2

  (rewrite using exponentials)

• Can I use a lifeline?

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?
