what is the purpose of a logarithm
7 Example 1 â Evaluating Logarithms Use the definition of logarithmic function to evaluate each logarithm at the indicated value of x. a. f (x) = log 2 x, x = 32 b. f (x) = log 3 x, x = 1 c. f (x) = log 4 x, x = 2 d. f (x) = log 10 x, x = Solution: a. f (32) = log 2 32 because 2 5 = 32.
