WebIn order to change base from b to c, we can use the logarithm change of base rule. The base b logarithm of x is equal to the base c logarithm of x divided by the base c logarithm of b: log b (x) = log c (x) / log c (b) Example #1. log 2 (100) = log 10 (100) / log 10 (2) = 2 / 0.30103 = 6.64386. Example #2. log 3 (50) = log 8 (50) / log 8 (3 ... Webthe change of base formula: logb a = loga a loga b But of course loga a = 1. That is, to get the value a, a should be raised to the power 1. (loga a = 1 is one of the laws of logarithms.) So we see that Special Case Formula: logb a = 1 loga b Example 3 Express loge as a natural logarithm. We know that loge means log10 e.
