["Because log (x) is the sum of the terms of the form log (1 + 2−k) corresponding to those k for which the factor 1 + 2−k was included in the product P, log (x) may be computed by simple addition, using a", "Logarithm integral The integral of logarithm of x: ∫ log b (x) dx = x ∙ ( log b (x) - 1 / ln (b) ) + C For example: ∫ log 2 (x) dx = x ∙ ( log 2 (x) - 1 / ln (2) ) + C Logarithm approximation log 2 (x) ≈ n + (x /2 n -", "Expressed in terms of common logarithms, this relationship is given by log mn = log m + log n. For example, 100 × 1,000 can be calculated by looking up the logarithms of 100 (2) and 1,000", "For example the result for 2 x = 5 can be given as a logarithm, x = log 2 (5) . You will learn how to evaluate this logarithmic expression over the following lessons.", "Learn the eight (8) log rules or laws to help you evaluate, expand, condense, and solve logarithmic equations.
