Question

Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. See Example 9.

log2 48

Answer 1

5.5854

Explanation:

Using the change of base formula,

Log 48 to base 2 = Log 48 ÷ Log 2

Log 48 = 1.6812

Log 2 = 0.3010

Log 48 ÷ Log 2 = 1.6812 ÷ 0.3010 = 5.5854
