WebFeb 17, 2024 · A: Concepts. Exercise 4.3e. A. 1) What is a base b logarithm? Discuss the meaning by interpreting each part of the equivalent equations by = x and logbx = y for b > 0, b ≠ 1. 2) How is the logarithmic function f(x) = logbx related to the exponential function g(x) = bx? What is the result of composing these two functions? WebLogarithms are a convenient way to express large numbers. (The base-10 logarithm of a number is roughly the number of digits in that number, for example.) Slide rules work because adding and subtracting logarithms is equivalent to multiplication and division. (This benefit is slightly less important today.) Lots of things "decay logarithmically".
