### Solving Exponential Equations Using Logarithms

Chapter 8.6

2 to what power = 7

• Solve 2x = 7

log 2x = log 7

1) Take the log of each side

log 2x = log 7

2) Use the Power Property

x log 2= log 7

3) Divide both sides by log 2

log 2

log 2

x = log 7

4) Use calculator to find the approximate value of x

≈ 2.807
