Logarithms
Method 2
Example 2
Solve the equation
Step 1. Use Power of a Power Property to convert to a single log.
Step 2. Use the inverse operation of exponents on both sides of the equals sign. Since the common log has a base of 10, use an exponential base of 10.
Step 3. Since logs and exponents are inverses, the exponent base and the log base cancel.
Step 4 . Solve for x.
