Answered: Travis Kent on 17 Dec 2020. In mathematics, the logarithm is the inverse function to exponentiation.That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.In the simplest case, the logarithm counts the number of occurrences of the same factor in repeated multiplication; e.g. Here is a sketch of a point in \({\mathbb{R}^3}\). The graph should contain the vertex, the y intercept, x-intercepts (if any) and at least one point on either side of the vertex. In mathematics, a complex logarithm is a generalization of the natural logarithm to nonzero complex numbers.The term refers to one of the following, which are strongly related: A complex logarithm of a nonzero complex number z, defined to be any complex number w for which e w = z.
