Furthermore, if u v = , then log log b b u v = . 5.4.34 Use the properties of logarithms and the logarithm property of equality to solve the equation. Objective 4: Using the Change of Base Formula Change of Base Formula For any positive base 1 b and for any positive real number u , then log log log a b a u u b = where a is any positive number such that 1 a . 5.4.40 Use the change of base formula and a calculator to approximate the following expressions. Do not round until the final answer. Then round to four decimal places as needed. 5.4.47 Solve the equation and simplify the answer....
