Witryna27 mar 2024 · By the definition of a logarithm, it is the inverse of an exponent. Therefore, a logarithmic function is the inverse of an exponential function. Recall what it means to be an inverse of a function. When two inverses are composed, they equal x. Therefore, if f(x) = bx and g(x) = logbx, then: f ∘ g = blogbx = x and g ∘ f = logbbx = x WitrynaA logarithm answers the question "How many of this number do we multiply to get that number?" Example How many 2s must we multiply to get 8? Answer: 2 × 2 × 2 = 8, so we had to multiply 3 of the 2s to get 8 We say the logarithm of 8 with base 2 is 3 In fact … WitrynaLogarithms or logs are a part of mathematics.They are related to exponential functions.A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiation.Historically, they were useful in multiplying or dividing large numbers. guyton football
